Struct fumio::reactor::Handle

pub struct Handle { /* fields omitted */ }

A (shared) handle to the reactor.

The handle is used to register new IO events (i.e. sockets to be polled).

Methods

impl Handle

pub fn waker(&self) -> Waker

A waker to interrupt the eventloop.

Also see Reactor::waker.

pub fn enter<F, T>(self, enter: &mut Enter, f: F) -> T where
    F: FnOnce(&mut Enter) -> T, 

Enter a reactor handle.

Clears the current handle when f returns.

current and LazyHandle need this to work.

A runtime (combining reactor, pool, ...) should enter a reactor handle (in each thread it runs tasks from the pool) so all tasks have access to the reactor.

Panics

Panics if a handle is already entered.
