use_callback

Memoize a function identity between renders.

Parameters:

• fn (Callable[P, R]) –

  A function to memoize.

• dependencies (Sequence[Any] | None, default: None ) –

  If present, fn is only re-memoized when one of the dependencies has changed. If absent, fn is only memoized on initial render.

Returns:

• Callable[P, R] –

  A memoized version of the function whose identity is stable between renders.
