Struct SignatureInfo

pub struct SignatureInfo {
    pub signature: SignatureType,
    pub der_encoded: DEREncoding,
    pub sig_hash: u8,
    pub length: usize,
}

Fields

signature: SignatureType

The actual signature wrapped in a type enum.

der_encoded: DEREncoding

Inidcates if a ECDSA signature is strictly DER encoded. A Schnorr signature will never be DER encoded always be DEREncoding::NotApplicable.

sig_hash: u8

SigHash flag of the signature.

length: usize

length of the encoded signature.

Implementations

impl SignatureInfo

pub fn low_s(&self) -> bool

pub fn low_r(&self) -> bool

pub fn from_instruction_ecdsa( instruction: &Instruction<'_>, ) -> Option<SignatureInfo>

Returns Some(SignatureInfo) if the Instruction is a Bitcoin ECDSA Signature, otherwise None is returned.

pub fn from_instruction_schnorr( instruction: &Instruction<'_>, ) -> Option<SignatureInfo>

Returns Some(SignatureInfo) if the Instruction is a Bitcoin Schnorr Signature, otherwise None is returned.

pub fn from_u8_slice_ecdsa(bytes: &[u8]) -> Option<SignatureInfo>

Returns Some(SignatureInfo) if the Instruction is a Bitcoin ECDSA Signature, otherwise None is returned.

pub fn from_u8_slice_schnorr(bytes: &[u8]) -> Option<SignatureInfo>

Returns Some(SignatureInfo) if the Instruction is a Bitcoin Schnorr Signature, otherwise None is returned.

pub fn all_from(input: &TxIn) -> Result<Vec<SignatureInfo>, InputError>

Constructs a vector of SignatureInfo for all Signatures in the input. If the inputs script_sig and witness don’t contain any signatures, an empty vector is returned.

Trait Implementations

impl Clone for SignatureInfo

fn clone(&self) -> SignatureInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignatureInfo

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

Formats the value using the given formatter.

impl PartialEq for SignatureInfo

fn eq(&self, other: &SignatureInfo) -> 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.
