Struct yewdux::context::Context

pub struct Context { /* private fields */ }

Execution context for a dispatch

Example

use yewdux::prelude::*;

#[derive(Clone, PartialEq, Default, Store)]
struct Counter(usize);

let cx = yewdux::Context::new();
let dispatch = Dispatch::<Counter>::new(&cx);

Implementations

impl Context

pub fn new() -> Self

pub fn global() -> Self

pub fn reduce<S: Store, R: Reducer<S>>(&self, r: R)

pub fn reduce_mut<S: Store + Clone, F: FnOnce(&mut S)>(&self, f: F)

pub fn set<S: Store>(&self, value: S)

Set state to given value.

pub fn get<S: Store>(&self) -> Rc<S>

Get current state.

pub fn notify_subscribers<S: Store>(&self, state: Rc<S>)

Send state to all subscribers.

pub fn subscribe<S: Store, N: Callable<S>>( &self, on_change: N ) -> SubscriberId<S>

Subscribe to a store. on_change is called immediately, then every time state changes.

pub fn subscribe_silent<S: Store, N: Callable<S>>( &self, on_change: N ) -> SubscriberId<S>

Similar to Self::subscribe, however state is not called immediately.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
