[][src]Enum glutin::event_loop::ControlFlow

pub enum ControlFlow {
    Poll,
    Wait,
    WaitUntil(Instant),
    Exit,
}

Set by the user callback given to the EventLoop::run method.

Indicates the desired behavior of the event loop after Event::RedrawEventsCleared is emitted. Defaults to Poll.

Persistency

Almost every change is persistent between multiple calls to the event loop closure within a given run loop. The only exception to this is Exit which, once set, cannot be unset. Changes are not persistent between multiple calls to run_return - issuing a new call will reset the control flow to Poll.

Variants

Poll

When the current loop iteration finishes, immediately begin a new iteration regardless of whether or not new events are available to process.

Platform-specific

Wait

When the current loop iteration finishes, suspend the thread until another event arrives.

WaitUntil(Instant)

When the current loop iteration finishes, suspend the thread until either another event arrives or the given time is reached.

Exit

Send a LoopDestroyed event and stop the event loop. This variant is sticky - once set, control_flow cannot be changed from Exit, and any future attempts to do so will result in the control_flow parameter being reset to Exit.
