Struct Computed 

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

A derived (computed) signal — read-only.

The value is recomputed on each Computed::get from the captured signals, so it is always up to date:

use dinamika_core::*;

let a = Signal::new(2.0_f32);
let b = Signal::new(3.0_f32);
let sum = {
    let (a, b) = (a.clone(), b.clone());
    Computed::new(move || a.get() + b.get())
};
assert_eq!(sum.get(), 5.0);
a.set(10.0);
assert_eq!(sum.get(), 13.0);

Implementations

impl<T> Computed<T>

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

Creates a computed signal from a closure.

pub fn get(&self) -> T

Recomputes and returns the current value.

Trait Implementations

impl<T> Clone for Computed<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
