Struct termimad::EventSource

pub struct EventSource { /* fields omitted */ }

a thread backed event listener emmiting events on a channel.

Additionnally to emmitting events, this source updates a sharable event count, protected by an Arc. This makes it easy for background computation to stop (or check if they should) when a user event is produced.

Implementations

impl EventSource

pub fn new() -> Result<EventSource, Error>

create a new source

If desired, mouse support must be enabled and disabled in crossterm.

pub fn unblock(&self, quit: bool)

either start listening again, or quit, depending on the passed bool. It’s mandatory to call this with quit=true at end for a proper ending of the thread (and its resources)

pub fn shared_event_count(&self) -> Arc<AtomicUsize>

return a shared reference to the event count. Other threads can use it to check whether something happened (when there’s no parallel computation, the event channel is usually enough).

pub fn receiver(&self) -> Receiver<Event>

return a new receiver for the channel emmiting events

pub fn escape_sequence_receiver(&self) -> Receiver<EscapeSequence>

return a new receiver for the channel emmiting escape sequences

It’s a bounded channel and any escape sequence will be dropped when it’s full

Trait Implementations

impl Drop for EventSource

fn drop(&mut self)

Executes the destructor for this type.
