Struct MailboxOwner 

pub struct MailboxOwner<U> { /* private fields */ }

Affine authority over user-message admission for an actor mailbox.

Unlike UserSender, this capability is deliberately not cloneable and does not expose a counting sender. Cloneable addresses are obtained as MailboxRefs instead. Consuming this owner with MailboxOwner::close_admission prevents every stale reference from acquiring a new delivery permit while allowing permits acquired before the close to finish. The consumer can then receive every accepted message followed by Received::UserLaneClosed.

Dropping the owner has the same admission-closing effect. The explicit method is preferred at graceful-retirement sites because it documents the lifecycle transition.

Implementations

impl<U> MailboxOwner<U>

pub fn actor_ref(&self) -> MailboxRef<U>

Create another non-owning, cloneable address for this mailbox.

pub fn close_admission(self)

Atomically close admission with respect to deliveries through every MailboxRef, including stale clones.

A racing delivery has exactly one of two outcomes: it acquired a temporary sender before this close and must be received before the terminal marker, or it receives its original payload back as closed. This operation does not destroy the consumer or discard queued work.

Trait Implementations

impl<U> Drop for MailboxOwner<U>

fn drop(&mut self)

Executes the destructor for this type.
