Struct k256::schnorr::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 as_bytes(&self) -> &[u8; 64]

Borrow the serialized signature as bytes.

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

Formats the value using the given formatter.

impl<D> DigestSigner<D, Signature> for SigningKeywhere
    D: Digest + FixedOutput<OutputSize = U32>,

fn try_sign_digest(&self, digest: D) -> Result<Signature>

Attempt to sign the given prehashed message [Digest], returning a digital signature on success, or an error if something went wrong.

fn sign_digest(&self, digest: D) -> S

Sign the given prehashed message [Digest], returning a signature.

impl<D> DigestVerifier<D, Signature> for VerifyingKeywhere
    D: Digest + FixedOutput<OutputSize = U32>,

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

Verify the signature against the given [Digest] output.

impl Ord for Signature

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Signature> for Signature

fn eq(&self, other: &Self) -> 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 PartialOrd<Signature> for Signature

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

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<D> RandomizedDigestSigner<D, Signature> for SigningKeywhere
