Struct DestructionWatcherSynchronousProxy 

pub struct DestructionWatcherSynchronousProxy { /* private fields */ }

Implementations

impl DestructionWatcherSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DestructionWatcherEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn watch( &self, ___deadline: MonotonicInstant, ) -> Result<Vec<IpSocketState>, Error>

Hanging get for destroyed sockets.

Returns sockets destroyed since the last call to this method. Blocks until at least one event is available.

A “destroyed” socket is one that no longer has any references inside the Netstack. Especially for TCP sockets (because of TIME-WAIT), this may happen long after close has returned.

Sockets destroyed before the watcher was created are not returned. Unbound sockets are not returned.

Only one call to Watch may be active at a time. Concurrency is not allowed and will result in the channel being closed with ALREADY_EXISTS.

If the client doesn’t read events fast enough, the channel is closed with NO_RESOURCES.
