use_memo

Memoize a computed value between renders.

Parameters:

  • calculate_value (Callable[[], MemoValueT]) –

    A function that computes the value to be memoized.

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

    If present, the value is only recomputed when one of the dependencies has changed. If absent, the value is only computed on initial render.

Returns:

  • MemoValueT –

    A memoized value whose identity is stable between renders.
