Trait alacritty::tty::EventedPty

pub trait EventedPty: EventedReadWrite {
    fn child_event_token(&self) -> Token;
    fn next_child_event(&mut self) -> Option<ChildEvent>;
}

A pseudoterminal (or PTY)

This is a refinement of EventedReadWrite that also provides a channel through which we can be notified if the PTY child process does something we care about (other than writing to the TTY). In particular, this allows for race-free child exit notification on UNIX (cf. SIGCHLD).

Required methods

fn child_event_token(&self) -> Token

fn next_child_event(&mut self) -> Option<ChildEvent>

Tries to retrieve an event

Returns Some(event) on success, or None if there are no events to retrieve.
