Struct SignalSurrogate 

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

Implementations

impl<T> SignalSurrogate<T>

where for<'b> &'b T: Surrogated,

pub fn read(&self) -> <&T as Surrogated>::Surrogate

Borrows the current value.

Reads inside a runtime expression are the client-reactive path and do not register a dependency on the server; the server-side evaluation only records whether the expression needs a browser binding.

impl<T> SignalSurrogate<T>

where T: Surrogated + Clone,

pub fn get(&self) -> <T as Surrogated>::Surrogate

Clones the current value.

Like read, this does not register a dependency on the server.

impl<T> SignalSurrogate<T>

where T: Surrogated,

pub fn set(&self, _v: T::Surrogate)

Writes a new value to the signal.

Panics

Always panics; signal writes can only occur in client-side expressions.

impl SignalSurrogate<bool>

pub fn toggle(&self)

Replaces the value with its negation.

Panics

Always panics; signal writes can only occur in client-side expressions.

impl SignalSurrogate<f64>

pub fn increment(&self)

Adds one to the value.

Panics

Always panics on the server. Integer overflow panics in the browser.

Panics

Always panics; signal writes can only occur in client-side expressions.

Trait Implementations

impl<T: Debug> Debug for SignalSurrogate<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for SignalSurrogate<T>

where T: Surrogated, T::Surrogate: Deserialize<'de>,

A signal sent by the client, as an argument to a run: its id next to its current value.

The value is required. A run cannot read a signal it has no value for, so a client that sends only the id is rejected the same way as one that sends a value of the wrong shape.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> RefCast for SignalSurrogate<T>

type From = Signal<T>

fn ref_cast(_from: &Self::From) -> &Self

fn ref_cast_mut(_from: &mut Self::From) -> &mut Self

impl<T> Serialize for SignalSurrogate<T>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Surrogate for SignalSurrogate<T>

type Real = Signal<T>

fn into_real(self) -> Self::Real

impl<'__lifetime, T> Surrogate for &'__lifetime SignalSurrogate<T>

type Real = &'__lifetime Signal<T>

fn into_real(self) -> Self::Real

impl<'__lifetime, T> Surrogate for &'__lifetime mut SignalSurrogate<T>

type Real = &'__lifetime mut Signal<T>
