Recursive Length Prefix encoding written in Swift

RLPSwift

This is a basic Swift implementation of Recursive Length Prefix Encoding, a serialisation method for encoding arbitrarily structured binary data (byte arrays).

You can read more about it here:

• Ethereum Wiki - RLP
• Ethereum Yellowpaper (Appendix B)

Interface

// Encoding Data
RLP.encode(_ data: Data) -> Data

// Encoding String
RLP.encode(_ string: String, with encoding: String.Encoding = .ascii) throws -> Data

// Encoding nested array of Data
RLP.encode(nestedArrayOfData array: [Any]) throws -> Data

// Encoding nested array of String
RLP.encode(nestedArrayOfString array: [Any], encodeStringsWith encoding: String.Encoding = .ascii) throws -> Data
