# Struct crossbeam::mem::CachePadded [−] [src]

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

Pad `T` to the length of a cacheline.

Sometimes concurrent programming requires a piece of data to be padded out to the size of a cacheline to avoid "false sharing": cachelines being invalidated due to unrelated concurrent activity. Use the `CachePadded` type when you want to avoid cache locality.

At the moment, cache lines are assumed to be 32 * sizeof(usize) on all architectures.

Warning: the wrapped data is never dropped; move out using `ptr::read` if you need to run dtors.

## Methods

### `impl<T: ZerosValid> CachePadded<T>`

#### `fn zeroed() -> CachePadded<T>`

A const fn equivalent to mem::zeroed().

### `impl<T> CachePadded<T>`

#### `fn new(t: T) -> CachePadded<T>`

Wrap `t` with cacheline padding.

Warning: the wrapped data is never dropped; move out using `ptr:read` if you need to run dtors.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
