Struct Computed 

pub struct Computed<T: Clone> { /* private fields */ }

A computed value (like Vue 3’s computed()). Lazily evaluates a closure, caching the result and re-evaluating when its dependencies change.

Implementations

impl<T: Clone + 'static> Computed<T>

pub fn new<F: Fn() -> T + 'static>(f: F) -> Self

Create a new computed value from the given computation function.

pub fn get(&self) -> Ref<'_, T>

Get the computed value. This will re-compute if dependencies have changed.
