Trait CellExt

pub trait CellExt<T>: Sealed {
    // Required methods
    fn get(&self) -> T
       where T: Clone + Default;
    fn with<F, R>(&self, f: F) -> R
       where T: Default,
             F: FnOnce(&T) -> R;
    fn with_mut<F, R>(&self, f: F) -> R
       where T: Default,
             F: FnOnce(&mut T) -> R;
}

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.

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.
