Trait reactive_graph::traits::ReadUntracked

pub trait ReadUntracked: Sized + DefinedAt {
    type Value: Deref;

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

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

Give read-only access to a signal’s value by reference through a guard type, without tracking the value reactively.

Required Associated Types

type Value: Deref

The guard type that will be returned, which can be dereferenced to the value.

Required Methods

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

Returns the guard, or None if the signal has already been disposed.

Provided Methods

fn read_untracked(&self) -> Self::Value

Returns the guard.

Panics

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

Object Safety

This trait is not object safe.
