Merge "Update smallvec to 1.8.0" am: 2b8efd428c am: 3d0e7105d4 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/smallvec/+/2004421 Change-Id: I2161ea8a48db4249effa6baee5ec05fc2178e3d1
“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();
