}Expand description
Converts a stream of bytes into Thrift identifiers, primitives, containers, or structs.
This trait does not deal with higher-level Thrift concepts like structs or
exceptions - only with primitives and message or container boundaries. Once
bytes are read they are deserialized and an identifier (for example
TMessageIdentifier) or a primitive is returned.
All methods return a thrift::Result. If an Err is returned the protocol
instance and its underlying transport should be terminated.
Required Methods
