WebbAPI documentation for the Rust `Hasher` trait in crate `std`. ... Despite its name, the method does not reset the hasher’s internal state. Additional writes will continue from the current value. If you need to start a fresh hash value, you will have to create a new hasher. WebbCreates an empty HashSet with at least the specified capacity, using hasher to hash the keys. The hash set will be able to hold at least capacity elements without reallocating. …
