[][src]Struct blake3::Hasher

pub struct Hasher { /* fields omitted */ }

An incremental hash state that can accept any number of writes.

Methods

impl Hasher[src]

pub fn new() -> Self[src]

Construct a new Hasher for the regular hash function.

pub fn new_keyed(key: &[u8; 32]) -> Self[src]

Construct a new Hasher for the keyed hash function. See keyed_hash.

pub fn new_derive_key(context: &str) -> Self[src]

Construct a new Hasher for the key derivation function. See derive_key. The context string should be hardcoded, globally unique, and application-specific.

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

Add input bytes to the hash state. You can call this any number of times.

Note that the degree of SIMD and multi-threading parallelism that Hasher can use is limited by the size of this input buffer. The 8 KiB buffer currently used by std::io::copy is enough to leverage AVX2, for example, but not enough to leverage AVX-512. If multi-threading is enabled (the rayon feature), the optimal input buffer size will vary considerably across different CPUs, and it may be several mebibytes.

pub fn finalize(&self) -> Hash[src]

Finalize the hash state and return the Hash of the input.

This method is idempotent. Calling it twice will give the same result. You can also add more input and finalize again.

Important traits for OutputReader
pub fn finalize_xof(&self) -> OutputReader[src]

Finalize the hash state and return an OutputReader, which can supply any number of output bytes.

This method is idempotent. Calling it twice will give the same result. You can also add more input and finalize again.
