Struct Waker 

pub struct Waker { /* private fields */ }

Wakes a driver blocked in Driver::turn from any thread. Cheap to clone; repeated wakes before the driver runs collapse into one OS signal.

Implementations

impl Waker

pub fn wake(&self)

Makes the driver’s current or next Driver::turn return Event::Wake.

pub fn post(&self)

Like Waker::wake, for work the caller has just queued for the driver’s thread (with a sequentially consistent push, such as crate::mpsc::Mpsc::push): the current or next Driver::turn returns Event::Wake, but the OS is signalled only when the driver is parked in it. A driver that is running, or spinning in its busy poll, picks the work up without a system call on either side, and posts that arrive together cost one signal.
