Struct valerie::state::StateAtomic

pub struct StateAtomic<T> { /* fields omitted */ }

State variable to be used with types that implement Copy

This uses AtomicCell of crossbeam internally.

Implementations

impl<T> StateAtomic<T>

pub fn new(value: T) -> Self

Make a new StateAtomic variable.

Examples

let state = StateAtomic::new(0);
h3!(state)

impl<T> StateAtomic<T> where
    T: Display + Copy + 'static, 

pub fn from<U, F>(state: &U, func: F) -> Self where
    U: StateTrait + 'static,
    F: FnMut(U::Value) -> Self::Value + 'static, 

Derive a StateAtomic variable from another variable implementing StateTrait.

Examples

let counter = StateAtomic::new(1);
let double_counter = StateAtomic::from(&counter, |x| x * 2);

div!(
    h3!("Single count ", counter),
    h3!("Double count ", double_counter)
)
