[−][src]Struct kuska_sodiumoxide::crypto::generichash::State
State contains the state for multi-part (streaming) hash computations. This allows the caller
to process a message as a sequence of multiple chunks.
Implementations
impl State[src]
pub fn new(out_len: usize, key: Option<&[u8]>) -> Result<State, ()>[src]
new constructs and initializes a new State with the given parameters.
out_len specifies the resulting hash size.
Only values in the interval [DIGEST_MIN, DIGEST_MAX] are allowed.
key is an optional parameter, which when given,
a custom key can be used for the computation of the hash.
The size of the key must be in the interval [KEY_MIN, KEY_MAX].
pub fn update(&mut self, data: &[u8]) -> Result<(), ()>[src]
update updates the State with data. update can be called multiple times in order
to compute the hash from sequential chunks of the message.
pub fn finalize(self) -> Result<Digest, ()>[src]
finalize finalizes the state and returns the digest value. finalize consumes the
State so that it cannot be accidentally reused.
