Struct InputSigner 

pub struct InputSigner { /* private fields */ }

An input signer.

Implementations

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<All>

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

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

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.

impl Debug for InputSigner

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

Formats the value using the given formatter.
