Expand description
Adds a closure to be called by the default main loop when it’s idle.
func
will be called repeatedly until it returns Continue(false)
.
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 idle_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 idle_add_local()
, this only requires func
to be
FnOnce
, and will automatically return Continue(false)
.
