Function use_computed_signal_with_prev

Source 
pub fn use_computed_signal_with_prev<T: 'static, D: PartialEq + Clone + 'static>(
    deps: D,
    init: impl Fn(Option<&mut T>) -> T,
) -> ReadOnlySignal<T>
Expand description

Alternative to use_memo Benefits:

  • No unnecessary rerenders
  • Access the previous computed value Downsides:
  • D needs to be Clone (cannot be avoided)
  • Prev value is &mut T instead of T
