match static method
Checks if the RawInput matches the expected format for a P2PKHInput, with or without a signature. If it does it returns a P2PKHInput for the input or else it returns null.
Implementation
static P2PKHInput? match(RawInput raw) {
final script = raw.script;
if (script == null) return null;
final ops = script.ops;
if (ops.isEmpty || ops.length > 2) return null;
final insig = ops.length == 2 ? ops[0].ecdsaSig : null;
if (insig == null && ops.length == 2) return null;
final publicKey = ops.last.publicKey;
if (publicKey == null) return null;
return P2PKHInput(
prevOut: raw.prevOut,
publicKey: publicKey,
insig: insig,
sequence: raw.sequence,
);
}
