Struct pw_tokenizer_core::Hasher

pub struct Hasher { /* private fields */ }

Hasher is used to calculate a token’s hash value.

The hash state is encapsulated in the Hasher to allow the hashing of multi-part strings where the concatenated value can not be know at macro expansion time. All functions are const.

Implementations

impl Hasher

pub const fn new(data_len: usize, hash_len: usize) -> Self

Create a new Hasher

data_len is the total length of the data to be hashed. hash_len is the number of bytes of data to be used in calculating the hash. data_len is used to seed the hash while hash_len controls how many bytes are hashed.

pub const fn process_bytes(self, bytes: &[u8]) -> Self

Processes bytes and updates hash state.

Consumes self and returns a Hasher with the updated state.

pub const fn hash(self) -> u32

Consume self and return the hash.
