Trait Write

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

    // Required methods
    fn try_write(&self) -> Option<impl UntrackableGuard>;
    fn try_write_untracked(&self) -> Option<impl DerefMut>;

    // Provided methods
    fn write(&self) -> impl UntrackableGuard { ... }
    fn write_untracked(&self) -> impl DerefMut { ... }
}

Gives mutable access to a signal’s value through a guard type. When the guard is dropped, the signal’s subscribers will be notified.

Required Associated Types

type Value: 'static

The type of the signal’s value.

Required Methods

fn try_write(&self) -> Option<impl UntrackableGuard>

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

fn try_write_untracked(&self) -> Option<impl DerefMut>

or None if the signal has already been disposed.

Provided Methods

fn write(&self) -> impl UntrackableGuard

Returns the guard.

Panics

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

fn write_untracked(&self) -> impl DerefMut

Returns a guard that will not notify subscribers when dropped.

Panics

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
