`rotate_left(n)` is equivalent to applying `rotate_left(1)` a total of `n` times. In particular, a rotation by the number of bits in `self` returns the input value unchanged.

Please note this isn’t the same operation as the `<<` shifting operator!

##### §Examples

    let n = 0xaa00000000006e1u64;
    let m = 0x6e10aa;

    assert_eq!(n.rotate_left(12), m);

#### pub const fn rotate_right(self, n: u32) -> u64

Shifts the bits to the right by a specified amount, `n`, wrapping the truncated bits to the beginning of the resulting integer.

`rotate_right(n)` is equivalent to applying `rotate_right(1)` a total of `n` times. In particular, a rotation by the number of bits in `self` returns the input value unchanged.

Please note this isn’t the same operation as the `>>` shifting operator!

##### §Examples

    let n = 0x6e10aau64;
    let m = 0xaa00000000006e1;

    assert_eq!(n.rotate_right(12), m);
    assert_eq!(n.rotate_right(1024), n);

#### pub const fn funnel_shl(self, rhs: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Performs a left funnel shift (concatenates `self` with `rhs`, with `self` making up the most significant half, then shifts the combined value left by `n`, and most significant half is extracted to produce the result).

Please note this isn’t the same operation as the `<<` shifting operator or `rotate_left`, although `a.funnel_shl(a, n)` is equivalent to `a.rotate_left(n)`.

##### §Panics

If `n` is greater than or equal to the number of bits in `self`

##### §Examples

Basic usage:

    #![feature(funnel_shifts)]
    let a = 0xaa00000000006e1u64;
    let b = 0x2fe78e45983acd98u64;
    let m = 0x6e12fe;

    assert_eq!(a.funnel_shl(b, 12), m);

Source

#### pub const fn funnel_shr(self, rhs: u64, n: u32) -> u64

🔬This is a nightly-only experimental API. (`funnel_shifts` #145686)

Performs a right funnel shift (concatenates `self` and `rhs`, with `self` making up the most significant half, then shifts the combined value right by `n`, and least significant half is extracted to produce the result).

Please note this isn’t the same operation as the `>>` shifting operator or `rotate_right`, although `a.funnel_shr(a, n)` is equivalent to `a.rotate_right(n)`.

##### §Panics

If `n` is greater than or equal to the number of bits in `self`

##### §Examples

Basic usage:

    #![feature(funnel_shifts)]
    let a = 0xaa00000000006e1u64;

The following panics because of overflow:

ⓘ

    let _ = (u64::MAX - 2).strict_add(3);

1.79.0 (const: 1.79.0) · Source

#### pub const unsafe fn unchecked_add(self, rhs: u64) -> u64

Unchecked integer addition. Computes `self + rhs`, assuming overflow cannot occur.

Calling `x.unchecked_add(y)` is semantically equivalent to calling `x.` `checked_add``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_add`.

##### §Safety

This results in undefined behavior when `self + rhs > u64::MAX` or `self + rhs < u64::MIN`, i.e. when `checked_add` would return `None`.

1.66.0 (const: 1.66.0) · Source

#### pub const fn checked_add_signed(self, rhs: i64) -> Option<u64>

Checked addition with a signed integer. Computes `self + rhs`, returning `None` if overflow occurred.

#### pub const fn checked_sub(self, rhs: u64) -> Option<u64>

Checked integer subtraction. Computes `self - rhs`, returning `None` if overflow occurred.

##### §Examples

    assert_eq!(0u64.checked_sub(1), None);

1.91.0 (const: 1.91.0) · Source

#### pub const fn strict_sub(self, rhs: u64) -> u64

Strict integer subtraction. Computes `self - rhs`, panicking if overflow occurred.

##### §Panics

###### §Overflow behavior

This function will always panic on overflow, regardless of whether overflow checks are enabled.

##### §Examples

    assert_eq!(1u64.strict_sub(1), 0);

The following panics because of overflow:

ⓘ

    let _ = 0u64.strict_sub(1);

1.79.0 (const: 1.79.0) · Source

#### pub const unsafe fn unchecked_sub(self, rhs: u64) -> u64

Unchecked integer subtraction. Computes `self - rhs`, assuming overflow cannot occur.

Calling `x.unchecked_sub(y)` is semantically equivalent to calling `x.` `checked_sub``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_sub`.

If you find yourself writing code like this:

    if foo >= bar {
        // SAFETY: just checked it will not overflow
        let diff = unsafe { foo.unchecked_sub(bar) };
        // ... use diff ...
    }

Consider changing it to

    if let Some(diff) = foo.checked_sub(bar) {
        // ... use diff ...
    }

As that does exactly the same thing – including telling the optimizer that the subtraction cannot overflow – but avoids needing `unsafe`.

##### §Safety

This results in undefined behavior when `self - rhs > u64::MAX` or `self - rhs < u64::MIN`, i.e. when `checked_sub` would return `None`.

#### pub const unsafe fn unchecked_disjoint_bitor(self, other: u64) -> u64

🔬This is a nightly-only experimental API. (`disjoint_bitor` #135758)

Same value as `self | other`, but UB if any bit position is set in both inputs.

This is a situational micro-optimization for places where you’d rather use addition on some platforms and bitwise or on other platforms, based on exactly which instructions combine better with whatever else you’re doing. Note that there’s no reason to bother using this for places where it’s clear from the operations involved that they can’t overlap. For example, if you’re combining `u16`s into a `u32` with `((a as u32) << 16) | (b as u32)`, that’s fine, as the backend will know those sides of the `|` are disjoint without needing help.

##### §Examples

    #![feature(disjoint_bitor)]

    // SAFETY: `1` and `4` have no bits in common.
    unsafe {
        assert_eq!(1_u64.unchecked_disjoint_bitor(4), 5);
    }

##### §Safety

Requires that `(self & other) == 0`, otherwise it’s immediate UB.

Equivalently, requires that `(self | other) == (self + other)`.

#### pub const fn wrapping_shl(self, rhs: u32) -> u64

Panic-free bitwise shift-left; yields `self << mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

Beware that, unlike most other `wrapping_*` methods on integers, this does not give the same result as doing the shift in infinite precision then truncating as needed. The behaviour matches what shift instructions do on many processors, and is what the `<<` operator does when overflow checks are disabled, but numerically it’s weird. Consider, instead, using `Self::unbounded_shl` which has nicer behaviour.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a `rotate_left` function, which may be what you want instead.

#### pub const fn wrapping_shr(self, rhs: u32) -> u64

Panic-free bitwise shift-right; yields `self >> mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

#### pub fn carrying_add(self, rhs: u64, carry: bool) -> (u64, bool)

Calculates `self` + `rhs` + `carry` and returns a tuple containing the sum and the output carry (in that order).

Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.

This can be thought of as a 64-bit “full adder”, in the electronics sense.

If the input carry is false, this method is equivalent to `overflowing_add`, and the output carry is equal to the overflow flag. Note that although carry and overflow flags are similar for unsigned integers, they are different for signed integers.

##### §Examples

    //    3  MAX    (a = 3 × 2^64 + 2^64 - 1)

Performs “ternary subtraction” by subtracting both an integer operand and a borrow-in bit from `self`, and returns an output integer and a borrow-out bit. This allows chaining together multiple subtractions to create a wider subtraction, and can be useful for bignum subtraction.

##### §Examples

#### pub const fn widening_mul(self, rhs: u64) -> (u64, u64)

🔬This is a nightly-only experimental API. (`bigint_helper_methods` #85532)

Calculates the complete double-width product `self * rhs`.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order. As such, `a.widening_mul(b).0` produces the same result as `a.wrapping_mul(b)`.

If you also need to add a value and carry to the wide result, then you want `Self::carrying_mul_add` instead.

If you also need to add a carry to the wide result, then you want `Self::carrying_mul` instead.

If you just want to know whether the multiplication overflowed, then you want `Self::overflowing_mul` instead.

##### §Examples

    #![feature(bigint_helper_methods)]
    assert_eq!(5_u64.widening_mul(7), (35, 0));
    assert_eq!(u64::MAX.widening_mul(u64::MAX), (1, u64::MAX - 1));

Compared to other `*_mul` methods:

    #![feature(bigint_helper_methods)]
    assert_eq!(u64::widening_mul(1 << 63, 6), (0, 3));
    assert_eq!(u64::overflowing_mul(1 << 63, 6), (0, true));

#### pub fn carrying_mul(self, rhs: u64, carry: u64) -> (u64, u64)

Calculates the “full multiplication” `self * rhs + carry` without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you also need to add a value, then use `Self::carrying_mul_add`.

##### §Examples

Please note that this example is shared among integer types, which is why `u32` is used.

    assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
    assert_eq!(5u32.carrying_mul(2, 10), (20, 0));
    assert_eq!(1_000_000_000u32.carrying_mul(10, 0), (1410065408, 2));
    assert_eq!(1_000_000_000u32.carrying_mul(10, 10), (1410065418, 2));
    assert_eq!(u64::MAX.carrying_mul(u64::MAX, u64::MAX), (0, u64::MAX));

This is the core operation needed for scalar multiplication when implementing it for wider-than-native types.

    #![feature(bigint_helper_methods)]
    fn scalar_mul_eq(little_endian_digits: &mut Vec<u16>, multiplicand: u16) {
        let mut carry = 0;
        for d in little_endian_digits.iter_mut() {
            (*d, carry) = d.carrying_mul(multiplicand, carry);
        }
        if carry != 0 {
            little_endian_digits.push(carry);
        }
    }

    let mut v = vec![10, 20];
    scalar_mul_eq(&mut v, 3);
    assert_eq!(v, [30, 60]);

    assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
    let mut v = vec![0x4321, 0x8765];
    scalar_mul_eq(&mut v, 0xFEED);
    assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);

If `carry` is zero, this is similar to `overflowing_mul`, except that it gives the value of the overflow instead of just whether one happened:

    #![feature(bigint_helper_methods)]
    let r = u8::carrying_mul(7, 13, 0);
    assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
    let r = u8::carrying_mul(13, 42, 0);
    assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));

The value of the first field in the returned tuple matches what you’d get by combining the `wrapping_mul` and `wrapping_add` methods:

    #![feature(bigint_helper_methods)]
    assert_eq!(
        789_u16.carrying_mul(456, 123).0,
        789_u16.wrapping_mul(456).wrapping_add(123),
    );

#### pub fn carrying_mul_add(self, rhs: u64, carry: u64, add: u64) -> (u64, u64)

Calculates the “full multiplication” `self * rhs + carry + add`.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

This cannot overflow, as the double-width result has exactly enough space for the largest possible result. This is equivalent to how, in decimal, 9 × 9 + 9 + 9 = 81 + 18 = 99 = 9×10⁰ + 9×10¹ = 10² - 1.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the `add` part, then you can use `Self::carrying_mul` instead.

##### §Examples

Please note that this example is shared between integer types, which explains why `u32` is used here.

    assert_eq!(5u32.carrying_mul_add(2, 0, 0), (10, 0));
    assert_eq!(5u32.carrying_mul_add(2, 10, 10), (30, 0));
    assert_eq!(1_000_000_000u32.carrying_mul_add(10, 0, 0), (1410065408, 2));
    assert_eq!(1_000_000_000u32.carrying_mul_add(10, 10, 10), (1410065428, 2));
    assert_eq!(u64::MAX.carrying_mul_add(u64::MAX, u64::MAX, u64::MAX), (u64::MAX, u64::MAX));

This is the core per-digit operation for “grade school” O(n²) multiplication.

Please note that this example is shared between integer types, using `u8` for simplicity of the demonstration.

    fn quadratic_mul<const N: usize>(a: [u8; N], b: [u8; N]) -> [u8; N] {
        let mut out = [0; N];

#### pub const fn is_multiple_of(self, rhs: u64) -> bool

Returns `true` if `self` is an integer multiple of `rhs`, and false otherwise.

This function is equivalent to `self % rhs == 0`, except that it will not panic for `rhs == 0`. Instead, `0.is_multiple_of(0) == true`, and for any non-zero `n`, `n.is_multiple_of(0) == false`.

##### §Examples

#### pub const fn next_power_of_two(self) -> u64

Returns the smallest power of two greater than or equal to `self`.

When return value overflows (i.e., `self > (1 << (N-1))` for type `uN`), it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which this method can return 0).

##### §Examples

    assert_eq!(2u64.next_power_of_two(), 2);
    assert_eq!(3u64.next_power_of_two(), 4);

1.0.0 (const: 1.50.0) · Source

#### pub const fn checked_next_power_of_two(self) -> Option<u64>

Returns the smallest power of two greater than or equal to `self`. If the next power of two is greater than the type’s maximum value, `None` is returned, otherwise the power of two is wrapped in `Some`.

##### §Examples

    assert_eq!(2u64.checked_next_power_of_two(), Some(2));

#### pub const fn from_str_radix(src: &str, radix: u32) -> Result<u64, ParseIntError>

Parses an integer from a string slice with digits in a given base.

The string is expected to be an optional `+` sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in Rust literals) also represent an error.

Digits are a subset of these characters, depending on `radix`:

- `0-9`
- `a-z`
- `A-Z`

##### §Panics

This function panics if `radix` is not in the range from 2 to 36.

##### §See also

If the string to be parsed is in base 10 (decimal), `from_str` or `str::parse` can also be used.

##### §Examples

    assert_eq!(u64::from_str_radix("A", 16), Ok(10));

Trailing space returns error:

    assert!(u64::from_str_radix("1 ", 10).is_err());

The characters are expected to be an optional `+` sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in Rust literals) also represent an error.

##### §Examples

    #![feature(int_from_ascii)]

    assert_eq!(u64::from_ascii(b"+10"), Ok(10));

Trailing space returns error:

    assert!(u64::from_ascii(b"1 ").is_err());

### impl FromStr for u64

Source§

#### fn from_str(src: &str) -> Result<u64, ParseIntError>

Parses an integer from a string slice with decimal digits.

The characters are expected to be an optional `+` sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in Rust literals) also represent an error.

##### §See also

For parsing numbers in other bases, such as binary or hexadecimal, see `from_str_radix`.

##### §Examples

    use std::str::FromStr;

    assert_eq!(u64::from_str("+10"), Ok(10));

Trailing space returns error:

    assert!(u64::from_str("1 ").is_err());
