Struct curve25519_dalek::ristretto::CompressedRistretto

source · [−]

pub struct CompressedRistretto(pub [u8; 32]);

Expand description

A Ristretto point, in compressed wire format.

The Ristretto encoding is canonical, so two points are equal if and only if their encodings are equal.

Tuple Fields

0: [u8; 32]

Implementations

source

impl CompressedRistretto

source

pub fn to_bytes(&self) -> [u8 ; 32]

Copy the bytes of this CompressedRistretto.

source

pub fn as_bytes(&self) -> &[u8 ; 32]

View this CompressedRistretto as an array of bytes.

source

pub fn from_slice(bytes: &[u8 ]) -> CompressedRistretto

Construct a CompressedRistretto from a slice of bytes.

Panics

If the input bytes slice does not have a length of 32.

source

pub fn decompress(&self) -> Option<RistrettoPoint>

Attempt to decompress to an RistrettoPoint.

Return

Some(RistrettoPoint) if self was the canonical encoding of a point;
None if self was not the canonical encoding of a point.
