Struct ed25519_dalek::Signature

pub struct Signature(_);

Ed25519 signature.

Implementations

impl Signature

pub const BYTE_SIZE: usize

Size of an encoded Ed25519 signature in bytes.

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

Parse an Ed25519 signature from a byte slice.

pub fn to_bytes(self) -> [u8; 64]

Return the inner byte array.

pub fn new(bytes: [u8; 64]) -> Signature

👎 Deprecated since 1.3.0:

use ed25519::Signature::from_bytes instead

DEPRECATED: Create a new signature from a byte array.

Warning

This method will panic if an invalid signature is encountered.

Use Signature::from_bytes or Signature::try_from instead for a fallible conversion.

Trait Implementations

impl AsRef<[u8]> for Signature

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

Performs the conversion.

impl Clone for Signature

pub 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

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

Formats the value using the given formatter.

impl Display for Signature

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

Formats the value using the given formatter.

impl From<[u8; 64]> for Signature

DEPRECATED: use TryFrom<&[u8]> instead.

Warning

This conversion will panic if a signature is invalid.

pub fn from(bytes: [u8; 64]) -> Signature

Performs the conversion.

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.

pub fn from_str(hex: &str) -> Result<Signature, Error>

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

impl LowerHex for Signature

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

Formats the value using the given formatter.

impl PartialEq<Signature> for Signature

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

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

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

This method tests for !=.

impl Signature for Signature

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

Parse a signature from its byte representation

fn as_bytes(&self) -> &[u8]

Borrow a byte slice representing the serialized form of this signature

impl Signer<Signature> for Keypair

fn try_sign(&self, message: &[u8]) -> Result<Signature, SignatureError>

Sign a message with this keypair’s secret key.

fn sign(&self, msg: &[u8]) -> S

Sign the given message and return a digital signature

impl<'_> TryFrom<&'_ [u8]> for Signature

type Error = Error

The type returned in the event of a conversion error.

pub fn try_from(bytes: &[u8]) -> Result<Signature, Error>

Performs the conversion.

impl UpperHex for Signature

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

Formats the value using the given formatter.

impl Verifier<Signature> for Keypair

fn verify(
    &self,
    message: &[u8],
    signature: &Signature
) -> Result<(), SignatureError>

Verify a signature on a message with this keypair’s public key.

impl Verifier<Signature> for PublicKey

fn verify(
    &self,
    message: &[u8],
    signature: &Signature
) -> Result<(), SignatureError>

Verify a signature on a message with this keypair’s public key.

Return

Returns Ok(()) if the signature is valid, and Err otherwise.
