Function sighash

pub(crate) fn sighash(
    precomputed_tx_data: &PrecomputedTxData<'_>,
    hash_type: HashType,
    input_index_script_code: Option<(usize, Vec<u8>)>,
) -> SigHash

Compute a signature hash using librustzcash.

Inputs

• precomputed_tx_data: precomputed data for the transaction whose signature hash is being computed.
• hash_type: the type of hash (SIGHASH) being used.
• input_index_script_code: a tuple with the index of the transparent Input for which we are producing a sighash and the respective script code being validated, or None if it’s a shielded input.
