A consistent view of the pre-epoch Membership state.

Used when consensus is operating before epochs are enabled (the epoch == None path in the legacy API).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
