Cache Line Size

This is a crate that gives access to the cache line size of a given architecture. It also has a generic type that can be used to align its parameter to the cache line size.

For example, to have a struct with three u8 with each on its own cache line, you could write the following code:

```rust

use cachelinesize::{CacheAligned, CACHELINESIZE}; use std::mem::size_of;

struct ThreeLineStruct { line1: CacheAligned, line2: CacheAligned, line_3: CacheAligned, }

[test]

fn itisthreelines() { asserteq!(sizeof::(), 3*CACHELINE_SIZE); }

```
