Struct curve25519_dalek::ristretto::CompressedRistretto

[+] Show declaration

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.

Implementations

impl CompressedRistretto[−]

pub fn to_bytes(&self) -> [u8; 32][−]

Copy the bytes of this CompressedRistretto.

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

View this CompressedRistretto as an array of bytes.

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.

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.
