Struct ConnectionIncarnationAllocator 

pub struct ConnectionIncarnationAllocator { /* private fields */ }

Validated monotonic connection-incarnation allocator state.

This state is intentionally not Copy or Clone: each transition consumes its pre-state and returns the one resulting state which must be committed.

Implementations

impl ConnectionIncarnationAllocator

pub const fn try_restore( restored: ConnectionIncarnationAllocatorRestore, ) -> Result<Self, ConnectionIncarnationAllocatorRestoreError>

Restores the durable fixed header after validating the terminal bit.

Errors

Returns ConnectionIncarnationAllocatorRestoreError unless ordinal u64::MAX and the exhaustion bit are either both present or both absent.

pub const fn server_incarnation(&self) -> u64

Returns the current durable server incarnation.

pub const fn last_examined_connection_ordinal(&self) -> Option<u64>

Returns the last allocated or collision-rejected connection ordinal.

pub const fn connection_ordinal_exhausted(&self) -> bool

Returns whether this server incarnation can never mint another ordinal.

pub const fn as_restore(&self) -> ConnectionIncarnationAllocatorRestore

Projects the exact fixed header which a binding must persist atomically.
