Function add_timer

pub fn add_timer(delay: u32, callback: Box<dyn FnMut() -> u32 + Send>) -> Timer

Available on crate feature dep_sdl3 only.

Constructs a new timer using the boxed closure callback.

The timer is started immediately and will be canceled either:

• When the timer is dropped.
• When the callback returns a non-positive continuation interval.

The callback is run in a thread that is created and managed internally by SDL3 from C. The callback must not panic!
