impl Clone for LocalStorage

fn clone(&self) -> LocalStorage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LocalStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Storage<T> for LocalStorage

where T: 'static,

type Wrapped = SendWrapper<T>

The type being stored, once it has been wrapped.

fn wrap(value: T) -> <LocalStorage as Storage<T>>::Wrapped

Adds any needed wrapper to the type.

fn try_with<U>(node: NodeId, fun: impl FnOnce(&T) -> U) -> Option<U>

Applies the given function to the stored value, if it exists and can be accessed from this thread.

fn try_with_mut<U>(node: NodeId, fun: impl FnOnce(&mut T) -> U) -> Option<U>

Applies the given function to a mutable reference to the stored value, if it exists and can be accessed from this thread.

fn try_set(node: NodeId, value: T) -> Option<T>

Sets a new value for the stored value. If it has been disposed, returns Some(T).

fn take(node: NodeId) -> Option<T>

Takes an item from the arena if it exists and can be accessed from this thread. If it cannot be casted, it will still be removed from the arena.
