Struct `Waker`

pub(crate) struct Waker { pub(in ::sync::mpmc::waker) selectors: Vec<Entry>, pub(in ::sync::mpmc::waker) observers: Vec<Entry> }

A queue of threads blocked on channel operations.

This data structure is used by threads to register blocking operations and get woken up once an operation becomes ready.

Fields

selectors: Vec<Entry>: A list of select operations.
observers: Vec<Entry>: A list of operations waiting to be ready.

Implementations

`impl Waker`

fn new() -> Self: Creates a new Waker.
fn register(&mut self, oper: Operation, cx: &Context): Registers a select operation.
fn register_with_packet(&mut self, oper: Operation, packet: *mut (), cx: &Context): Registers a select operation and a packet.
fn unregister(&mut self, oper: Operation) -> Option<Entry>: Unregisters a select operation.
fn try_select(&mut self) -> Option<Entry>: Attempts to find another thread's entry, select the operation, and wake it up.
fn notify(&mut self): Notifies all operations waiting to be ready.
fn disconnect(&mut self): Notifies all registered operations that the channel is disconnected.
