Expand description

Adds a closure to be called by the main loop the returned Source is attached to at regular intervals with millisecond granularity.

func will be called repeatedly every interval milliseconds until it returns ControlFlow::Break. Precise timing is not guaranteed, the timeout may be delayed by other events. Prefer timeout_add_seconds when millisecond precision is not necessary.
