Struct GroupMetadata 

pub struct GroupMetadata { /* private fields */ }

A member’s identity and its fencing token, opaque above the seam.

Nothing outside this module reads the fields. They are what TxnOffsetCommit must carry so the coordinator can reject a commit from a member that has already been replaced (KIP-447), and under KIP-848 the same two positions hold a member epoch instead of a generation. A caller that could name them would be a caller that has to change when the protocol does, so the only way to get one is to ask a live consumer for it and hand it straight to a producer.
