Extension trait for PSBT input signing

Required methods

fn sign_input_pretr<C, R>(
    &mut self,
    txin: &TxIn,
    index: usize,
    provider: &impl SecretProvider<C>,
    sig_hasher: &mut SigHashCache<R>
) -> Result<usize, SignInputError> where
    C: Signing,
    R: Deref<Target = Transaction>, 

Signs a single PSBT input using all known keys provided by SecretProvider. This includes signing legacy and segwit inputs only; including inputs coming from P2PK, P2PKH, P2WPKH, P2WPKH-in-P2SH, bare scripts, P2SH, P2WSH, P2WSH-in-P2SH.

For P2TR input signing use [SignInput::sign_input_tr] method.

This method supports all consensus sighash types.

Returns

Number of created signatures or error.
