Struct basalt::interval::Interval

source ·
pub struct Interval { /* private fields */ }
Expand description

The main struct for the interval system.

Accessed via basalt.interval_ref() or basalt.interval().

Implementations§

Call the method at provided internval.

Takes a Fn(last_call: Option<Duration>) -> IntvlHookCtrl.

  • last_call: Duration since the last method was called.
  • delay: is the duration that has to elapsed after Interval::start(...) before the hook method is called.
  • IntvlHookCtrl: controls how the hook is handled after the method is called.
Notes
  • Hooks are paused to begin with. They must be started with Interval::start(...).
  • last_call will only be Some if the method is called continuously. Returning InputHookCtrl::Pause or using Interval::pause(...) will cause the next call to be None.
