Struct btc_transaction_utils::InputSignatureRef

pub struct InputSignatureRef<'a>(_);

A borrowed equivalent of the InputSignature data type. It can be useful for checking incoming signatures from unauthorized sources.

Examples

use secp256k1::Secp256k1;
use btc_transaction_utils::InputSignatureRef;

// Get a signature from the unknown source.
let bytes = hex::decode(
    "304402201538279618a4626653775069b43d4315c7d2ff3000\
     8d339d0ed31ff41e628e71022028f3182fc39df28201ca4d7d\
     489aece7bc5bc6bfe05b09b6a9d3b70bf5f3743101",
).unwrap();
// Try to decode it.
let signature = InputSignatureRef::from_bytes(&bytes)
    .expect("Signature should be correct");

Methods

impl<'a> InputSignatureRef<'a>

pub fn from_bytes(bytes: &'a [u8]) -> Result<InputSignatureRef<'a>, Error>

Tries to construct input signature from the raw bytes.

pub fn content(&self) -> &[u8]

Returns the signature content in canonical form.

pub fn sighash_type(&self) -> SigHashType

Returns a sighash type of the given input signature.
