Struct Context 

pub struct Context<T>(/* private fields */);

Implementations

impl<T> Context<T>

where T: 'static,

pub fn new(initial: T) -> Self

pub fn receive() -> Self

Panics when there is no context with this type created

Trait Implementations

impl<T> Clone for Context<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Context<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Context<T>

fn eq(&self, other: &Context<T>) -> 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<T> SignalBase<T> for Context<T>

fn base(&self) -> Signal<T>

Returns the underlying signal of the concrete implementation.

impl<T> SignalGetter<T> for Context<T>

where T: Clone + 'static,

fn peek(&self) -> T

Returns the current value of the signal without tracking updates.

fn value(&self) -> T

Return the value of the signal and appends it to the current scope’s dependencies. If the values changes, the scope gets reexecuted to update to the new value.

impl<T> SignalSetter<T> for Context<T>

where T: PartialEq + 'static,

fn set(&self, value: impl Into<T>) -> T

Sets the value of the signal and notifies all dependencies.

impl<T> SignalUpdater<T> for Context<T>

where T: 'static,

fn update<U>(&self, updater: impl FnOnce(&mut T) -> U) -> U

Updates the signal value without cloning it using the provided updater function and notifies all dependencies. This will happen, no matter if the value acually changed or not.

fn set_unchecked(&self, value: impl Into<T>)

Sets the value of the signal and notifies all its dependencies.

impl<T> Copy for Context<T>

impl<T: Eq> Eq for Context<T>

impl<T> StructuralPartialEq for Context<T>
