The hash brown crate is used * It exposes some more APIs like `RawEntry`, which can avoid hashing / looking up elements twice. * It is slightly faster than the version included with Rust std, not only because of aHash (vs SipHasher used in std), but also some further optimizations / inlining. I think best would be to define a `HashMap` type alias, so we can use whatever is set by default across the project. -- This is an automated message from the Apache Git Service.
