impl MainContext
[src]
pub fn prepare(&self) -> (bool, i32)
[src]
pub fn find_source_by_id(&self, source_id: &SourceId) -> Option<Source>
[src]
pub fn invoke<F>(&self, func: F) where
F: FnOnce() + Send + 'static,
[src]
F: FnOnce() + Send + 'static,
Invokes func
on the main context.
pub fn invoke_with_priority<F>(&self, priority: Priority, func: F) where
F: FnOnce() + Send + 'static,
[src]
F: FnOnce() + Send + 'static,
Invokes func
on the main context with the given priority.
pub fn invoke_local<F>(&self, func: F) where
F: FnOnce() + 'static,
[src]
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.
pub fn invoke_local_with_priority<F>(&self, priority: Priority, func: F) where
F: FnOnce() + 'static,
[src]
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.
pub fn with_thread_default<R, F: Sized>(&self, func: F) -> R where
F: FnOnce() -> R,
[src]
F: FnOnce() -> R,
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.
impl MainContext
[src]
pub fn channel<T>(priority: Priority) -> (Sender<T>, Receiver<T>)
[src]
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
.
pub fn sync_channel<T>(
priority: Priority,
bound: usize
) -> (SyncSender<T>, Receiver<T>)
[src]
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
.
