Trait SignalValue 

pub trait SignalValue: Sized {
    type Surrogate<'a>: Serialize
       where Self: 'a;

    // Required methods
    fn surrogate(&self) -> Self::Surrogate<'_>;
    fn from_value(value: &Value) -> Option<Self>;
}

A value that can be sent to the browser and restored from browser state.

Implemented automatically for runtime types whose surrogates support serialization and deserialization.

Required Associated Types

type Surrogate<'a>: Serialize where Self: 'a

The serializable surrogate of a borrowed value.

Required Methods

fn surrogate(&self) -> Self::Surrogate<'_>

Borrows the value as its surrogate.

fn from_value(value: &Value) -> Option<Self>

Reads a value back from the surrogate a client sent, or None if the surrogate does not fit this type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<T> SignalValue for T

where T: Surrogated, T::Surrogate: DeserializeOwned, for<'a> &'a T: Surrogated, for<'a> <&'a T as Surrogated>::Surrogate: Serialize,

type Surrogate<'a> = <&'a T as Surrogated>::Surrogate where Self: 'a
