Struct std::cell::Cell 1.0.0
[−]
[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]
fn new(value: T) -> Cell<T>
Creates a new Cell containing the given value.
Examples
use std::cell::Cell; let c = Cell::new(5);Run
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();Run
fn set(&self, value: T)
fn as_unsafe_cell(&self) -> &UnsafeCell<T>
: renamed to as_ptr
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
fn as_ptr(&self) -> *mut T1.12.0
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
fn get_mut(&mut self) -> &mut T1.11.0
