Snap for 8358640 from 638d0ee87b2ef1082fe674e75f89932b179fe32a to mainline-go-media-release Change-Id: Ia6206be7c7cb0ed2e68681fb53476bc6cf558733
“Small vector” optimization for Rust: store up to a small number of items on the stack
use smallvec::{SmallVec, smallvec}; // This SmallVec can hold up to 4 items on the stack: let mut v: SmallVec<[i32; 4]> = smallvec![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();
