pub fn from_bytes(bytes: &SignatureBytes) -> Result<Self>

Parse an Ed25519 signature from a byte slice.

pub fn from_components(R: ComponentBytes, s: ComponentBytes) -> Result<Self>

Parse an Ed25519 signature from its R and s components.

pub fn r_bytes(&self) -> &ComponentBytes

Bytes for the R component of a signature.

pub fn s_bytes(&self) -> &ComponentBytes

Bytes for the s component of a signature.

pub fn to_bytes(&self) -> SignatureBytes

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

Available on crate feature alloc only.

Convert this signature into a byte vector.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

Available on crate feature serde only.

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

Deserialize this value from the given Serde deserializer.

impl<'de> Deserialize<'de> for Signature

Available on crate feature serde_bytes only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

impl Display for Signature

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

Formats the value using the given formatter.

impl From<&Signature> for SignatureBytes

fn from(sig: &Signature) -> SignatureBytes

Converts to this type from the input type.

impl From<Signature> for SignatureBytes

fn from(sig: Signature) -> SignatureBytes

Converts to this type from the input type.

impl FromStr for Signature

Decode a signature from hexadecimal.

Upper and lower case hexadecimal are both accepted, however mixed case is rejected.

type Err = Error

The associated error which can be returned from parsing.

fn from_str(hex: &str) -> Result<Self>

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

impl LowerHex for Signature

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

Formats the value using the given formatter.

impl PartialEq<Signature> for Signature

fn eq(&self, other: &Signature) -> 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 Serialize for Signature

Available on crate feature serde only.

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

Serialize this value into the given Serde serializer.

impl Serialize for Signature

Available on crate feature serde_bytes only.

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

impl SignatureEncoding for Signature

type Repr = [u8; 64]

fn try_from(bytes: &SignatureBytes) -> Result<Self>

Performs the conversion.

impl TryFrom<&[u8]> for Signature

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self>
