Struct redox::cell::Cell [−] [src]

pub struct Cell<T> {
    // some fields omitted
}

A mutable memory location that admits only Copy data.

See the module-level documentation for more.

Methods

impl<T> Cell<T> where T: Copy

fn new(value: T) -> Cell<T>

Creates a new Cell containing the given value.

Examples

use std::cell::Cell;

let c = Cell::new(5);

fn get(&self) -> T

Returns a copy of the contained value.

Examples

use std::cell::Cell;

let c = Cell::new(5);

let five = c.get();

fn set(&self, value: T)

Sets the contained value.

Examples

use std::cell::Cell;

let c = Cell::new(5);

c.set(10);

unsafe fn as_unsafe_cell(&self) -> &UnsafeCell<T>

Unstable (as_unsafe_cell)

Returns a reference to the underlying UnsafeCell.

Safety

This function is unsafe because UnsafeCell's field is public.

Examples

#![feature(as_unsafe_cell)]

use std::cell::Cell;

let c = Cell::new(5);

let uc = unsafe { c.as_unsafe_cell() };
