Struct Signature 

pub struct Signature(/* private fields */);

An Ed25519 signature (64 bytes).

Implementations

impl Signature

pub const fn from_bytes(bytes: [u8; 64]) -> Self

Create from raw bytes.

pub fn try_from_slice(slice: &[u8]) -> CryptoResult<Self>

Try to create from a slice.

Errors

Returns CryptoError::InvalidSignatureLength if the slice is not exactly 64 bytes.

pub const fn as_bytes(&self) -> &[u8; 64]

Get the raw bytes.

pub fn to_hex(&self) -> String

Encode as hex string.

pub fn from_hex(s: &str) -> CryptoResult<Self>

Decode from hex string.

Errors

Returns an error if the string is not valid hex or not 64 bytes.

pub fn to_base64(&self) -> String

Encode as base64 string.

pub fn from_base64(s: &str) -> CryptoResult<Self>

Decode from base64 string.

Errors

Returns an error if the string is not valid base64 or not 64 bytes.

pub fn verify(&self, message: &[u8], public_key: &[u8; 32]) -> CryptoResult<()>

Verify this signature against a message and public key.

Errors

Returns an error if the public key is invalid or signature verification fails.

pub fn to_dalek(&self) -> DalekSignature

Convert to the underlying dalek signature type.

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 duplicate 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

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl From<[u8; 64]> for Signature

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

Converts to this type from the input type.

impl From<Signature> for [u8; 64]

fn from(sig: Signature) -> Self

Converts to this type from the input type.

impl From<Signature> for Signature

fn from(sig: DalekSignature) -> Self

Converts to this type from the input type.

impl From<Signature> for Signature

fn from(sig: Signature) -> Self

Converts to this type from the input type.

impl PartialEq for Signature

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
