Add smallvec/OWNERS am: 5986c40c21 am: ce62492438 am: 7302d7a516 am: 61884b4153 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/smallvec/+/1429448 Change-Id: I8e36f6b3e62c9113e1a76bc57f227a71d0c40ba7
“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();
