Struct Hasher 

pub struct Hasher { /* private fields */ }

Incremental BLAKE3 hasher.

Wraps blake3::Hasher so callers don’t need to depend on the blake3 crate directly. Use Hasher::update in any order to mix in inputs; the resulting CacheKey is deterministic for a given sequence of updates.

Implementations

impl Hasher

pub fn new() -> Self

pub fn update(&mut self, bytes: &[u8]) -> &mut Self

pub fn update_u32(&mut self, value: u32) -> &mut Self

Mix in a u32 in little-endian. Useful for embedding numeric discriminants (target arch, opt level, schema version, …) into a key without committing to a string encoding.

pub fn update_u64(&mut self, value: u64) -> &mut Self

Mix in a u64 in little-endian.

pub fn update_str(&mut self, s: &str) -> &mut Self

Mix in a length-prefixed byte string. Use this instead of bare update when concatenating multiple variable-length fields, so that ("ab", "c") and ("a", "bc") don’t collide.

pub fn finalize(self) -> CacheKey

Trait Implementations

impl Default for Hasher

fn default() -> Hasher

Returns the “default value” for a type.
