pub fn timeout_add_seconds<F>(interval: u32, func: F) -> SourceId where
F: FnMut() -> Continue + Send + 'static,
Adds a closure to be called by the default main loop at regular intervals with second granularity.
func will be called repeatedly every
interval seconds until it
Continue(false). Precise timing is not guaranteed, the timeout may
be delayed by other events.
The default main loop almost always is the main loop of the main thread. Thus the closure is called on the main thread.
