Struct SendBufferTracking

pub struct SendBufferTracking<L> { /* private fields */ }

Tracks the available send buffer space for a socket.

Implementations

impl<L> SendBufferTracking<L>

pub fn new(capacity: PositiveIsize, listener: L) -> Self

Creates a new SendBufferTracking with the initial available send buffer space capacity and a writable listener listener.

impl<L: SocketWritableListener> SendBufferTracking<L>

pub fn acquire( &self, bytes: PositiveIsize, ) -> Result<SendBufferSpace, SendBufferFullError>

Acquires bytes for send with this SendBufferTracking instance.

pub fn release(&self, space: SendBufferSpace)

Releases space back to this SendBufferTracking instance.

pub fn capacity(&self) -> PositiveIsize

Returns the tracker’s capacity.

pub fn available(&self) -> Option<PositiveIsize>

Returns the currently available buffer space.

pub fn set_capacity(&self, new_capacity: PositiveIsize)

Updates the tracker’s capacity to new_capacity.

Note that upon changing the capacity the socket’s writable state may change.
