Upgrade rust/crates/smallvec to 1.4.1 am: 1e6392f230 am: 5a0931aed9 am: 210bfb1ee4 am: 9e821675c0 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/smallvec/+/1381197 Change-Id: I6c8e89ce752e5c457dd13aab9790e8e57708268b
“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();
