Struct diem_sdk::crypto::ed25519::ed25519_dalek::Signature

pub struct Signature(_);

Ed25519 signature.

Implementations

impl Signature

pub const BYTE_SIZE: usize = 64usize

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.

Panics

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

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

Converts this type into a shared reference of the (usually inferred) input type.

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<(), Error>

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl From<&Signature> for [u8; 64]

fn from(sig: &Signature) -> [u8; 64]

Converts to this type from the input type.

impl From<[u8; 64]> for Signature

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

Warning

This conversion will panic if a signature is invalid.

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

Converts to this type from the input type.

impl From<InternalSignature> for Signature

fn from(sig: InternalSignature) -> Signature

Converts to this type from the input type.

impl From<Signature> for [u8; 64]

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

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<Signature, Error>

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

impl LowerHex for Signature

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

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

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

Serialize this value into the given Serde serializer.

impl Signature for Signature

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, Error>

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.

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

Performs the conversion.

impl UpperHex for Signature

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<(), Error>

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<(), Error>

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

Return

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

impl Copy for Signature
