Trait that describes a Handshake Transaction

Required Associated Types

type WTXID: MarkedDigestOutput

The MarkedDigest type for the Transaction’s Witness TXID

type Witness

A type that represents this transactions per-input Witness.

Required Methods

fn new<I, O, W>(
    version: u32,
    vin: I,
    vout: O,
    witnesses: W,
    locktime: u32
) -> Result<Self, Self::TxError> where
    I: Into<Vec<Self::TxIn>>,
    O: Into<Vec<Self::TxOut>>,
    W: Into<Vec<Self::Witness>>,
    Self: Sized, 

Instantiate a new WitnessTx from the arguments.

fn wtxid(&self) -> Self::WTXID

Calculates the witness txid of the transaction.

fn write_txid_preimage<W: Write>(
    &self,
    writer: &mut W
) -> Result<usize, Self::Error>

Computes the txid preimage.

fn write_wtxid_preimage<W: Write>(
    &self,
    writer: &mut W
) -> Result<usize, Self::Error>

Computes the wtxid preimage.

Provided Methods

fn signature_hash(
    &self,
    args: &Self::SighashArgs
) -> Result<Blake2b256Digest, Self::TxError>

Calculates the BIP143 sighash given the sighash args. See the WitnessSighashArgsSigh documentation for more in-depth discussion of sighash.
