Make libsmallvec available to resolv module am: 8ae8fd4570 am: fda98b38d8 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/smallvec/+/2535584 Change-Id: Ied4b64fe22cf370e8407fa74d57caf56b838f927 Signed-off-by: Automerger Merge Worker <[email protected]>
“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();
