Struct btc_transaction_utils::p2wpk::InputSigner

pub struct InputSigner { /* fields omitted */ }

An input signer.

Methods

impl InputSigner

pub fn new(public_key: PublicKey, network: Network) -> InputSigner

Creates an input signer for the given public key and network.

pub fn secp256k1_context(&self) -> &Secp256k1

Returns a reference to the secp256k1 engine, used to execute all signature operations.

pub fn secp256k1_context_mut(&mut self) -> &mut Secp256k1

Returns a mutable reference to the secp256k1 engine, used to execute all signature operations.

pub fn signature_hash<'a, 'b, V: Into<UnspentTxOutValue<'b>>>(
    &mut self,
    txin: TxInRef<'a>,
    value: V
) -> Sha256dHash

Computes the BIP-143 compliant sighash for a SIGHASH_ALL signature for the given input.

pub fn sign_input<'a, 'b, V: Into<UnspentTxOutValue<'b>>>(
    &mut self,
    txin: TxInRef<'a>,
    value: V,
    secret_key: &SecretKey
) -> Result<InputSignature, Error>

Computes the BIP-143 compliant signature for the given input. Under the hood this method signs sighash for the given input with the given secret key.

pub fn verify_input<'a, 'b, 'c, V, S>(
    &self,
    txin: TxInRef<'a>,
    value: V,
    public_key: &PublicKey,
    signature: S
) -> Result<(), Error> where
    V: Into<UnspentTxOutValue<'b>>,
    S: Into<InputSignatureRef<'c>>, 

Checks correctness of the signature for the given input.

pub fn spend_input(&self, input: &mut TxIn, signature: InputSignature)

Collects the witness data for the given transaction input. Thus, the input becomes spent.

Trait Implementations

impl Debug for InputSigner

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
