Struct massa_signature::PublicKeyV0

pub struct PublicKeyV0(VerifyingKey);

Public key used to check if a message was encoded by the corresponding PublicKey. Generated from the KeyPair using SignatureEngine

Tuple Fields

0: VerifyingKey

Implementations

impl PublicKeyV0

pub const PUBLIC_KEY_SIZE_BYTES: usize = 32usize

Size of a public key

pub fn get_ser_len(&self) -> usize

Return the total length after serialization

pub fn verify_signature( &self, hash: &Hash, signature: &SignatureV0 ) -> Result<(), MassaSignatureError>

Checks if the Signature associated with data bytes was produced with the KeyPair associated to given PublicKey

pub fn to_bytes(&self) -> Vec<u8>

Return the bytes representing the keypair (should be a reference in the future)

Example

let keypair = KeyPair::generate(0).unwrap();
let bytes = keypair.to_bytes();

pub fn from_bytes(data: &[u8]) -> Result<PublicKeyV0, MassaSignatureError>

Deserialize a PublicKey from bytes.

IMPORTANT: providing more bytes than needed does not result in an error.

Example

let keypair = KeyPair::generate(0).unwrap();

let serialized = keypair.get_public_key().to_bytes();
let deserialized: PublicKey = PublicKey::from_bytes(&serialized).unwrap();

Trait Implementations

impl Clone for PublicKeyV0

fn clone(&self) -> PublicKeyV0

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKeyV0

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

Formats the value using the given formatter.

impl Display for PublicKeyV0

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

Formats the value using the given formatter.

impl Hash for PublicKeyV0

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 PublicKeyV0

fn cmp(&self, other: &PublicKeyV0) -> 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<PublicKeyV0> for PublicKeyV0

fn eq(&self, other: &PublicKeyV0) -> 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 PartialOrd<PublicKeyV0> for PublicKeyV0

fn partial_cmp(&self, other: &PublicKeyV0) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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.
