Struct curve25519_dalek::ristretto::CompressedRistretto

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

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

impl CompressedRistretto

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

Copy the bytes of this CompressedRistretto.

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

View this CompressedRistretto as an array of bytes.

pub fn from_slice( bytes: &[u8], ) -> Result<CompressedRistretto, TryFromSliceError>

Construct a CompressedRistretto from a slice of bytes.

Errors

Returns TryFromSliceError 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.

Trait Implementations

impl Clone for CompressedRistretto

fn clone(&self) -> CompressedRistretto

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConstantTimeEq for CompressedRistretto

fn ct_eq(&self, other: &CompressedRistretto) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for CompressedRistretto

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CompressedRistretto

fn default() -> CompressedRistretto

Returns the “default value” for a type.

impl Hash for CompressedRistretto

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Identity for CompressedRistretto

fn identity() -> CompressedRistretto

Returns the identity element of the curve. Can be used as a constructor.

impl PartialEq for CompressedRistretto

fn eq(&self, other: &CompressedRistretto) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&[u8]> for CompressedRistretto

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<CompressedRistretto, TryFromSliceError>

Performs the conversion.

impl Zeroize for CompressedRistretto

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Copy for CompressedRistretto
