Source 
pub trait NotifyWaiterInterface<OS: OsInterface>: Send {
    // Required method
    fn wait(&self, timeout: &Duration<OS>) -> bool;

    // Provided method
    fn wait_with<U>(
        &self,
        timeout: &Duration<OS>,
        f: impl FnMut() -> Option<U>,
    ) -> Option<U> { ... }

Required Methods§

Source

fn wait(&self, timeout: &Duration<OS>) -> bool

Wait until notified or timeout occurs.

§Returns
  • true notified
  • false timeout occurred

Provided Methods§

Source

fn wait_with<U>( &self, timeout: &Duration<OS>, f: impl FnMut() -> Option<U>, ) -> Option<U>

§Description

Wait for a notification, and call your function to check anything you want when receiving a notification. You can control whether or not to continue waiting for the next notification.

§Parameters
  • timeout: Total timeout.
  • f: Your function. If it returns Some(x), it will break out of the wait.
§Returns
  • None: It’s timeout.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
