Struct SignatureIdentifier 

pub struct SignatureIdentifier { /* private fields */ }

Digital signature identifier with algorithm identification

The output contains:

• 1 byte: algorithm identifier
• N bytes: actual signature value (length depends on algorithm)

pub fn algorithm(&self) -> DSAlgorithm

Get the algorithm used

pub fn signature_bytes(&self) -> &[u8]

Get the signature bytes (without identifier)

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

Get the full bytes including algorithm identifier

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CryptoError>

Parse from bytes (includes algorithm identifier)

pub fn verify( &self, message: &[u8], public_key: &[u8], ) -> Result<(), CryptoError>

Trait Implementations

impl BorshDeserialize for SignatureIdentifier

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for SignatureIdentifier

impl Clone for SignatureIdentifier

fn clone(&self) -> SignatureIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureIdentifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SignatureIdentifier

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SignatureIdentifier

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

Formats the value using the given formatter.

impl FromStr for SignatureIdentifier

type Err = CryptoError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for SignatureIdentifier

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 SignatureIdentifier

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SignatureIdentifier

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SignatureIdentifier

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for SignatureIdentifier

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
