Throttling & Debouncing#

Throttling and debouncing are techniques used to prevent a frequently-emitted signal from triggering a specific callback more than some amount in a specified amount of time.

Throttling means preventing a callback from being called if it has recently been called; it is useful when the callback is expensive. See psygnal.throttled.

Debouncing means waiting for a period of time to pass before calling the callback; it is useful when you'd like to wait a moment to see if a user might do additional actions (say, moving a slider or typing in a text field) before "committing" to calling the callback. See psygnal.debounced.
