Created by cell().

Implementations§

source§

impl<T> Cell<T>
where T: MeshField + Sync + Clone,

source

pub fn get(&self) -> T
where T: Clone,

Gets a clone of the cell’s current value.

source

pub fn with<F, R>(&self, f: F) -> R
where F: FnOnce(&T) -> R,

Runs f with a reference to the cell’s current value.

While f is running, updates to the cell’s value will not be acknowledged (and the remote updater’s set method will block).

source

pub fn with_mut<F, R>(&self, f: F) -> R
where F: FnOnce(&mut T) -> R,

Runs f with a mutable reference to the cell’s current value.

While f is running, updates to the cell’s value will not be acknowledged (and the remote updater’s set method will block).

source

pub async fn wait_next(&mut self)

Waits for a new value to be set.
