Struct Signature 

pub struct Signature { /* private fields */ }

Ed448 signature.

This type represents a container for the byte serialization of an Ed448 signature, and does not necessarily represent well-formed field or curve elements.

Signature verification libraries are expected to reject invalid field elements at the time a signature is verified.

Implementations

impl Signature

pub const BYTE_SIZE: usize

Size of an encoded Ed448 signature in bytes (114-bytes).

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

Parse an Ed448 signature from a byte slice.

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

Parse an Ed448 signature from a byte slice.

Errors

• Returns Error if the input byte slice is not 114-bytes.

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

Return the inner byte array.

pub fn from_components( r: impl Into<ComponentBytes>, s: impl Into<ComponentBytes>, ) -> Self

Create a Signature from the serialized r and s component values which comprise the signature.

Deserialize this value from the given Serde deserializer.

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

Available on crate features serde and 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<&[u8; 114]> for Signature

fn from(bytes: &SignatureBytes) -> Self

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 From<[u8; 114]> for Signature

fn from(bytes: SignatureBytes) -> Self

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 Hash for Signature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for Signature

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

Formats the value using the given formatter.

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.
