Trait WriteValue 

pub trait WriteValue: Sized + DefinedAt {
    type Value: 'static;

    // Required method
    fn try_write_value(&self) -> Option<UntrackedWriteGuard<Self::Value>>;

    // Provided method
    fn write_value(&self) -> UntrackedWriteGuard<Self::Value> { ... }
}

A variation of the Write trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.

Required Associated Types

type Value: 'static

The type of the value’s value.

Required Methods

fn try_write_value(&self) -> Option<UntrackedWriteGuard<Self::Value>>

Returns a non-reactive write guard, or None if the value has already been disposed.

Provided Methods

fn write_value(&self) -> UntrackedWriteGuard<Self::Value>

Returns a non-reactive write guard.

Panics

Panics if you try to access a value that has been disposed.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl<T, S> WriteValue for StoredValue<T, S>

where T: 'static, S: Storage<ArcStoredValue<T>>,

type Value = T

impl<T> WriteValue for ArcStoredValue<T>

where T: 'static,

type Value = T
