pub struct AppContext { /* private fields */ }

The application context for managing the application lifecycle.

Implementations

impl AppContext

pub fn new(update: UpdateManager, diagnostics: Diagnostics) -> Self

Create a new application context using the given UpdateManager.

pub fn diagnostics(&self) -> Diagnostics

Get the Diagnostics of the application.

pub fn update(&self) -> UpdateManager

Get the UpdateManager of the application.

pub fn exit(&self)

Make the application exit by setting Update::EXIT.

pub fn hook_signal<T: 'static, S: Signal<T>>(&self, signal: &mut S)

Hook the given Signal to the UpdateManager of this application.

This makes the signal reactive, so it will notify the renderer when the inner value changes.

pub fn use_signal<T: 'static, S: Signal<T>>(&self, signal: S) -> S

Hook the given Signal to the UpdateManager of this application and return it.

See AppContext::hook_signal for more.

pub fn use_state<T: 'static>(&self, value: T) -> StateSignal<T>

Shortcut for creating and hooking a StateSignal into the application lifecycle.

pub fn use_memoized<T: 'static>( &self, value: impl Fn() -> T + 'static, ) -> MemoizedSignal<T>

Shortcut for creating and hooking a MemoizedSignal into the application lifecycle.

pub fn use_fixed<T: 'static>(&self, value: T) -> FixedSignal<T>

Shortcut for creating and hooking a FixedSignal into the application lifecycle.

pub fn use_eval<T: 'static>( &self, eval: impl Fn() -> T + 'static, ) -> EvalSignal<T>

Shortcut for creating and hooking an EvalSignal into the application lifecycle.

Trait Implementations

impl Clone for AppContext

fn clone(&self) -> AppContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.
