You add hashbrown as an explicit dependency? The standard library HashMap is a re-export of hashbrown. Doesn’t it work for you?

[vlovich123]

Can’t speak for the op but there’s a number of high performance interfaces that avoid redundant computations that are only available directly from hashbrown.

huh, does it? I always add it so I can make non-deterministic hashmaps in rust. oh and you need one more one for the hashing function I think.

But I did not know hashmap re-exported hashbrown, thanks.

Yep, they’re the same since Rust 1.36 (Jul 2019) - https://blog.rust-lang.org/2019/07/04/Rust-1.36.0/

looks like there's no way to access it, outside of hashmap.

Though maybe you just need the third party hasher and you can call with_hasher.

IDK man there's a lot going on with rust.

Yes that’s exactly it. If speed is a priority and the input is trusted, change the hasher to something faster like ahash. The ahash crate makes this easy.
