Struct Signature

pub struct Signature { /* private fields */ }

Available on crate feature schnorr only.

Taproot Schnorr signature as defined in BIP340.

Implementations

impl Signature

pub const BYTE_SIZE: usize = 64usize

Size of a Taproot Schnorr signature in bytes.

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

Serialize this signature as bytes.

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<(), Error>

Formats the value using the given formatter.

impl<D> DigestVerifier<D, Signature> for VerifyingKey

where D: Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>> + FixedOutput,

fn verify_digest(&self, digest: D, signature: &Signature) -> Result<(), Error>

Verify the signature against the given Digest output.

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 PrehashSignature for Signature

type Digest = CoreWrapper<CtVariableCoreWrapper<Sha256VarCore, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, OidSha256>>

Preferred Digest algorithm to use when computing this signature type.

impl PrehashVerifier<Signature> for VerifyingKey

fn verify_prehash( &self, prehash: &[u8], signature: &Signature, ) -> Result<(), Error>

Use Self to verify that the provided signature for a given message prehash is authentic.

impl SignatureEncoding for Signature

type Repr = [u8; 64]

Byte representation of a signature.

fn to_bytes(&self) -> <Signature as SignatureEncoding>::Repr

Encode signature as its byte representation.

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

Available on crate feature alloc only.

Encode signature as a byte vector.

fn encoded_len(&self) -> usize

Get the length of this signature when encoded.

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 Verifier<Signature> for VerifyingKey

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

Use Self to verify that the provided signature for a given message bytestring is authentic.

impl Copy for Signature

impl Eq for Signature
