Release notes

"Small vector" optimization for Rust: store up to a small number of items on the stack

Example

use smallvec::SmallVec;

// This SmallVec can hold up to 4 items on the stack:
let mut v: SmallVec<i32, 4> = SmallVec::from([1, 2, 3, 4]);

// It will automatically move its contents to the heap if
// contains more than four items:
v.push(5);

// SmallVec points to a slice, so you can use normal slice
// indexing and other methods to access its contents:
v[0] = v[1] + v[2];
v.sort();
