Trait PeekInterruptSource 

pub trait PeekInterruptSource: Send + 'static {
    // Required method
    fn poll_interrupt(&mut self, cx: &mut Context<'_>) -> Poll<()>;
}

Available on crate feature std only.

A condition that triggers a PeekInterrupt once it is met.

Sources are polled only while a peek waits for more input, see PeekInterrupt::attach.

Required Methods

fn poll_interrupt(&mut self, cx: &mut Context<'_>) -> Poll<()>

Poll whether the condition is met.

Once this returns Poll::Ready the interrupt stays triggered and the source is not polled again.

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety".
