Struct ed25519_consensus::VerificationKeyBytes

pub struct VerificationKeyBytes(_);

A refinement type for [u8; 32] indicating that the bytes represent an encoding of an Ed25519 verification key.

This is useful for representing an encoded verification key, while the VerificationKey type in this library caches other decoded state used in signature verification.

A VerificationKeyBytes can be used to verify a single signature using the following idiom:

use core::convert::TryFrom;
VerificationKey::try_from(vk_bytes)
    .and_then(|vk| vk.verify(&sig, msg));

Implementations

impl VerificationKeyBytes

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

Returns the byte encoding of the verification key.

This is the same as .into(), but does not require type inference.

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

View the byte encoding of the verification key.

Trait Implementations

impl Clone for VerificationKeyBytes

fn clone(&self) -> VerificationKeyBytes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> From<&'a SigningKey> for VerificationKeyBytes

fn from(sk: &'a SigningKey) -> VerificationKeyBytes

Converts to this type from the input type.

impl From<[u8; 32]> for VerificationKeyBytes

fn from(bytes: [u8; 32]) -> VerificationKeyBytes

Converts to this type from the input type.

impl From<VerificationKey> for VerificationKeyBytes

fn from(vk: VerificationKey) -> VerificationKeyBytes

Converts to this type from the input type.

impl From<VerificationKeyBytes> for [u8; 32]

fn from(refined: VerificationKeyBytes) -> [u8; 32]

Converts to this type from the input type.

impl Hash for VerificationKeyBytes

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 Ord for VerificationKeyBytes

fn cmp(&self, other: &VerificationKeyBytes) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<VerificationKeyBytes> for VerificationKeyBytes

fn eq(&self, other: &VerificationKeyBytes) -> 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.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
