Struct std::cell::Cell1.0.0 [] [src]

pub struct Cell<T> { /* 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
[src]

Creates a new Cell containing the given value.

Examples

use std::cell::Cell;

let c = Cell::new(5);Run

Returns a copy of the contained value.

Examples

use std::cell::Cell;

let c = Cell::new(5);

let five = c.get();Run

Sets the contained value.

Examples

use std::cell::Cell;

let c = Cell::new(5);

c.set(10);Run

Deprecated since 1.12.0

: renamed to as_ptr

Unstable (as_unsafe_cell #27708)

Returns a reference to the underlying UnsafeCell.

Examples

#![feature(as_unsafe_cell)]

use std::cell::Cell;

let c = Cell::new(5);

let uc = c.as_unsafe_cell();Run

Returns a raw pointer to the underlying data in this cell.

Examples

use std::cell::Cell;

let c = Cell::new(5);

let ptr = c.as_ptr();Run

Returns a mutable reference to the underlying data.

This call borrows Cell mutably (at compile-time) which guarantees that we possess the only reference.

Examples

use std::cell::Cell;

let mut c = Cell::new(5);
*c.get_mut() += 1;

assert_eq!(c.get(), 6);Run
