Struct async_timer::timer::PosixTimer

pub struct PosixTimer { /* fields omitted */ }

Posix Timer

When using c_wrapper feature implementation uses C shim to create timers which call callbacks from a separate thread.

Without it, callback is called from signal handler which limits usable operations within the callback.

impl PosixTimer

pub const fn new(time: Duration) -> Self

Creates new instance

Trait Implementations

impl Drop for PosixTimer

fn drop(&mut self)
