Struct Waker 

pub struct Waker { /* private fields */ }

A self-pipe used to wake a Poller blocked in wait from another thread. Register read_fd() in the poller for read-readiness; call wake() from any thread to make the poll return; call drain() when the read end fires.

Implementations

impl Waker

pub fn read_fd(&self) -> i32

The read end — register this in a Poller for read-readiness.

pub fn wake(&self) -> Result<()>

Signal the waker. A full pipe already means “pending”, so EAGAIN is fine.

pub fn drain(&self)

Consume all pending wake bytes after the read end fires.

Trait Implementations

impl Drop for Waker

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
