impl MainContext

Source

pub fn prepare(&self) -> (bool, i32)

Source

pub fn find_source_by_id(&self, source_id: &SourceId) -> Option<Source>

Source

pub fn invoke<F>(&self, func: F)
where F: FnOnce() + Send + 'static,

Invokes func on the main context.

Source

pub fn invoke_with_priority<F>(&self, priority: Priority, func: F)
where F: FnOnce() + Send + 'static,

Invokes func on the main context with the given priority.

Source

pub fn invoke_local<F>(&self, func: F)
where F: FnOnce() + 'static,

Invokes func on the main context.

Different to invoke(), this does not require func to be Send but can only be called from the thread that owns the main context.

This function panics if called from a different thread than the one that owns the main context.

Source

pub fn invoke_local_with_priority<F>(&self, priority: Priority, func: F)
where F: FnOnce() + 'static,

Invokes func on the main context with the given priority.

Different to invoke_with_priority(), this does not require func to be Send but can only be called from the thread that owns the main context.

This function panics if called from a different thread than the one that owns the main context.

Source

pub fn with_thread_default<R, F>(&self, func: F) -> R
where F: FnOnce() -> R + Sized,

Calls closure with context configured as the thread default one.

Thread default context is changed in panic-safe manner by calling push_thread_default before calling closure and pop_thread_default afterwards regardless of whether closure panicked or not.

Source§

impl MainContext

Source

pub fn channel<T>(priority: Priority) -> (Sender<T>, Receiver<T>)

Creates a channel for a main context.

The Receiver has to be attached to a main context at a later time, together with a closure that will be called for every item sent to a Sender.

The Sender can be cloned and both the Sender and Receiver can be sent to different threads as long as the item type implements the Send trait.

When the last Sender is dropped the channel is removed from the main context. If the Receiver is dropped and not attached to a main context all sending to the Sender will fail.

The returned Sender behaves the same as std::sync::mpsc::Sender.

Source

pub fn sync_channel<T>( priority: Priority, bound: usize, ) -> (SyncSender<T>, Receiver<T>)

Creates a synchronous channel for a main context with a given bound on the capacity of the channel.

The Receiver has to be attached to a main context at a later time, together with a closure that will be called for every item sent to a SyncSender.

The SyncSender can be cloned and both the SyncSender and Receiver can be sent to different threads as long as the item type implements the Send trait.

When the last SyncSender is dropped the channel is removed from the main context. If the Receiver is dropped and not attached to a main context all sending to the SyncSender will fail.

The returned SyncSender behaves the same as std::sync::mpsc::SyncSender.
