It is a logic error for a key to be modified in such a way that the key's hash, as determined by the Hash trait, or its equality, as determined by the Eq trait, changes while it is in the map. This is normally only possible through Cell, RefCell, global state, I/O, or unsafe code.

For a more representative performance comparison which includes the overhead of using a HashMap, see HashBrown's benchmarks as HashBrown now uses aHash as its hasher by default. Hash quality. AHash passes the full SMHasher test suite. The code to reproduce the result, and the full output are checked into the repo. Additional FAQ

Hashing. HashSet and HashMap are two widely-used types. The default hashing algorithm is not specified, but at the time of writing the default is an algorithm called SipHash 1-3. This algorithm is high quality—it provides high protection against collisions—but is relatively slow, particularly for short keys such as integers.Uses hashbrown for the inner table, just like Rust's libstd HashMap does. Performance. IndexMap derives a couple of performance facts directly from how it is constructed, which is roughly: A raw hash table of key-value indices, and a vector of key-value pairs. Iteration is very fast since it is on the dense key-values.As hashbrown is what powers the standard library hashmap, this is also available in nightly Rust as HashMap::get_many_mut. Unsafe code If you can guarantee that your two indices are different, you can use unsafe code and avoid interior mutability:Crate hashbrown [−] This crate is a Rust port of Google's high-performance SwissTable hash map, adapted to make it a drop-in replacement for Rust's standard HashMap and HashSet types.

It's not clear to me where the documentation indicates this.Creates a new empty hash table without allocating any memory. In effect this returns a table with exactly 1 bucket. However we can leave the data pointer dangling since that bucket is never written to due to our load factor forcing us to always have at least 1 free bucket.use hashbrown::HashMap; // Type inference lets us omit an explicit type signature (which // would be `HashMap<String, String>` in this example). let mut book_reviews = HashMap::new(); // Review some books. book_reviews.insert( "Adventures of Huckleberry Finn".to_string(), "My favorite book."

Creates an empty HashMap which will use the given hash builder to hash keys. The created map has the default initial capacity.
