Struct bee_crypto::ternary::sponge::CurlP

pub struct CurlP { /* fields omitted */ }

State of the ternary cryptographic function CurlP.

Implementations

impl CurlP

pub fn new(rounds: CurlPRounds) -> Self

Create a new CurlP sponge with rounds of iterations.

Trait Implementations

impl Sponge for CurlP

type Error = Infallible

An error indicating that a failure has occured during a sponge operation.

fn reset(&mut self)

Reset the internal state by overwriting it with zeros.

fn absorb(&mut self, input: &Trits) -> Result<(), Self::Error>

Absorb input into the sponge by copying HASH_LENGTH chunks of it into its internal state and transforming the state before moving on to the next chunk.

If input is not a multiple of HASH_LENGTH with the last chunk having n < HASH_LENGTH trits, the last chunk will be copied to the first n slots of the internal state. The remaining data in the internal state is then just the result of the last transformation before the data was copied, and will be reused for the next transformation.

fn squeeze_into(&mut self, buf: &mut Trits) -> Result<(), Self::Error>

Squeeze the sponge by copying the state into the provided buf. This will fill the buffer in chunks of HASH_LENGTH at a time.

If the last chunk is smaller than HASH_LENGTH, then only the fraction that fits is written into it.

fn squeeze(&mut self) -> Result<TritBuf, Self::Error>

Convenience function using Sponge::squeeze_into to return an owned output.

fn digest_into(
    &mut self,
    input: &Trits,
    buf: &mut Trits
) -> Result<(), Self::Error>

Convenience function to absorb input, squeeze the sponge into buf, and reset the sponge.

fn digest(&mut self, input: &Trits) -> Result<TritBuf, Self::Error>

Convenience function to absorb input, squeeze the sponge, reset the sponge and return an owned output.
