How to Implement RLP

[UrsaMajor-t]

RLP decoding of data in the circuit, is there an example of implementation?

Didn't see a RLP decoding snippet; some thoughts; if the length & types the input is not known, any decoding-in-circuit will be quite expensive. It might make more sense to do the decoding out-of-circuit and provide decoded inputs as a witness to the circuit.
