Struct StateHandle 

pub struct StateHandle<T: 'static>(/* private fields */);

A readonly Signal.

Returned by functions that provide a handle to access state. Use Signal::handle or Signal::into_handle to retrieve a handle from a Signal.

Implementations

impl<T: 'static> StateHandle<T>

pub fn get(&self) -> Rc<T>

Get the current value of the state.

pub fn get_untracked(&self) -> Rc<T>

Get the current value of the state, without tracking this as a dependency if inside a reactive context.

Example

use maple_core::prelude::*;

let state = Signal::new(1);

let double = create_memo({
    let state = state.clone();
    move || *state.get_untracked() * 2
});

assert_eq!(*double.get(), 2);

state.set(2);
// double value should still be old value because state was untracked
assert_eq!(*double.get(), 2);
