Struct StateSetter

pub struct StateSetter<T: 'static> { /* private fields */ }

Provides a setter for a piece of state managed by state.

Implementations

impl<T: 'static> StateSetter<T>

pub fn update<F: FnOnce(&mut T) + 'static>(&self, f: F)

Takes a function that modifies the state associated with the setter and triggers a rerender of its associated component.

The update is not performed immediately; its effect will only be accessible on its component’s rerender. Note that update always triggers a rerender, and the state value is marked as updated, even if the given function performs no mutations.

pub fn set(&self, val: T)

Sets the state to the given value.

The update is not performed immediately; its effect will only be accessible on its component’s rerender. Note that set always triggers a rerender, and the state value is marked as updated, even if the new state is equal to the old.

Trait Implementations

impl<T: 'static> Clone for StateSetter<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
