Struct Scope 

pub struct Scope { /* private fields */ }

Ownership scope for signals/effects (§4.3). Copy handle; not Send.

Implementations

impl Scope

pub fn current() -> Scope

pub fn root() -> Scope

pub fn child() -> Scope

Create a child of the current scope.

pub fn create_child(self) -> Scope

pub fn detached() -> Scope

A scope owned by nobody — dispose it manually.

pub fn enter<R>(self, f: impl FnOnce() -> R) -> R

Run f with self as the current scope.

pub fn on_cleanup(self, f: impl FnOnce() + 'static)

pub fn is_alive(self) -> bool

pub fn dispose(self)

Dispose this scope: children first, then own nodes (unsubscribed + dropped) and cleanups.

pub fn provide<T>(self, value: T)

where T: 'static,

Provide a context value visible to this scope and its descendants.

pub fn use_context<T>(self) -> Option<T>

where T: Clone + 'static,

Look up a context value here or in any ancestor (requires T: Clone).

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for Scope

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Scope

impl Eq for Scope

impl StructuralPartialEq for Scope
