Struct SyncSender

source
pub struct SyncSender<T> { /* private fields */ }
Expand description

The sender end of a synchronous channel

It can be cloned and sent accross threads (if T is).

Implementations§

source§

impl<T> SyncSender<T>

source

pub fn send(&self, t: T) -> Result<(), SendError<T>>

Send a message to the synchronous channel

This will wake the event loop and deliver an Event::Msg to it containing the provided value. If the channel is full, this function will block until the event loop empties it and it can deliver the message.

Due to the blocking behavior, this method should not be used on the same thread as the one running the event loop, as it could cause deadlocks.

source

pub fn try_send(&self, t: T) -> Result<(), TrySendError<T>>

Send a message to the synchronous channel

This will wake the event loop and deliver an Event::Msg to it containing the provided value. If the channel is full, this function will return an error, but the event loop will still be signaled for readiness.
