Crate hash_str

Macros§

hash_literal: Takes a string literal as input and hashes it, returning a u64 literal.
hstr: Construct a &’static HashStr at compile time. These are presumably deduplicated by the compiler.

HashStr: HashStr is a dynamically sized type so it is used similarly to &str. A hash is stored at the beginning followed by a str. The length is known by the fat pointer when in the form &HashStr.
HashedStr: A type that can be used in HashStrCache like HashStr but does not require allocation. Useful for reusing the hash without needing to create a HashStr. Used internally as part of the Presence struct to pass the hash and str along a cache chain.
UnhashedStr: Helper type for indexing a HashMap without allocation Unhashed str is hashed on the fly instead of using a precalculated hash. Useful for indexing a HashMap without needing to allocate a Box

HashStrMap: A standard HashMap using &HashStr as the key type with a custom Hasher that just uses the precomputed hash for speed instead of calculating it.
HashStrSet: A standard HashSet using &HashStr as the key type with a custom Hasher that just uses the precomputed hash for speed instead of calculating it.
