Struct wasm_react::hooks::State

source · [−]

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

Expand description

Allows access to the underlying state data persisted with use_state().

Implementations

source

impl<T: 'static> State<T>

source

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

Returns a reference to the value of the state.

source

pub fn set(&mut self, mutator: impl FnOnce(T) -> T)

Sets the state to the return value of the given mutator closure and rerenders the component.

Panics

Panics if the value is currently borrowed.
