pub fn unix_signal_add_local_once<F>(signum: i32, func: F) -> SourceIdwhere
F: FnOnce() + 'static,
Available on Unix only.
Expand description
Adds a closure to be called by the default main loop whenever a UNIX signal is raised.
func
will be called repeatedly every time signum
is raised until it
returns ControlFlow::Break
.
The default main loop almost always is the main loop of the main thread. Thus, the closure is called on the main thread.
Different to unix_signal_add()
, 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.
In comparison to unix_signal_add_local()
, this only requires func
to be
FnOnce
, and will automatically return ControlFlow::Break
.
