It soon will be the standard hashmap!

Does it still provide the DoS protection SipHash offered, or does that mean that Rust is moving from secure-by-default to fastest-by-default when it comes to HashMap ? If so it's kind of a big philosophical switch.

Hashbrown is not about the hashing algorithm. It uses fx hash which is pretty commonly used in Rust. I imagine they will still keep SipHash

OK thanks. But that would mean the performance gain would not be as dramatic I guess ?
