About smallvec
"Small vector" optimization for Rust: store up to a small number of items on the stack
Example
use ;
// This SmallVec can hold up to 4 items on the stack:
let mut v: = smallvec!;
// It will automatically move its contents to the heap if
// contains more than four items:
v.push;
// SmallVec points to a slice, so you can use normal slice
// indexing and other methods to access its contents:
v = v + v;
v.sort;
