## Detailed Description

Metadata is information about a particular gRPC™ call or channel (such as authentication details) in the form of a list of key-value pairs, where the keys are strings and the values are typically strings, but can be binary data. The class provides the possibility to store data in an unordered container. Also, it is possible to store several values by the same key.
