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".
