Function sv::transaction::sighash::sighash

pub fn sighash(
    tx: &Tx, 
    n_input: usize, 
    script_code: &[u8], 
    amount: Amount, 
    sighash_type: u8, 
    cache: &mut SigHashCache
) -> Result<Hash256>

Generates a transaction digest for signing

This will use either BIP-143 or the legacy algorithm depending on if SIGHASH_FORKID is set.
