Struct intuitive::render::hooks::State

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

A container for a T which causes re-renders when mutated, returned by UseState::use_state.

State is created through UseState::use_state.

Implementations

impl<T> State<T>

pub fn get(&self) -> Twhere
    T: Clone,

Returns a clone of the inner T.

pub fn set(&self, new: T) -> Result<()>

Sets the inner value of this State and enqueues a re-render.

Errors

Will return an Err if enqueueing the re-render fails.

pub fn mutate<F, R>(&self, f: F) -> Result<R>where
    F: FnOnce(&mut T) -> R,

Mutates the inner value of this State using the provided function, returning its return value, and enqueues a re-render.

Errors

Will return an Err if enqueueing the re-render fails.

pub fn update<F>(&self, f: F) -> Result<()>where
    F: FnOnce(&T) -> T,

Updates the inner value of this State with the return value of the provided function and enqueues a re-render.

Errors

Will return an Err if enqueueing the re-render fails.

Trait Implementations
