Trait cell_ref::CellExt

pub trait CellExt<T>: Sealed {
    fn get(&self) -> T
    where
        T: Clone + Default;
    fn with<F, R>(&self, f: F) -> R
    where

Provides additional methods for non-Copy types.

Required Methods

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

Gets the value held by the cell.

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

Calls f with a reference to the contents of the cell.

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

Calls f with a mutable reference to the contents of the cell.
