MessagePack for Swift

Swift implementation for MessagePack.

Packing

protocol Packable {
    func packToBytes() -> Bytes
    func pack() -> Data
}

Packable stdlib types:

• Bool, Double, Int, UInt, Int64, UInt64
• Optional where Wrapped : Packable
• Array where Element: Packable
• Dictionary where Key: Hashable, Key: Packable, Value: Packable

Packable extended types:

• Binary
• Extension

If you want to pack data with mixed types, use ValueBox.

Unpacking

struct Unpacker {
    static func unpack(bytes: Bytes) -> ValueBox?
}

Unpack from data, conveniences for Unpacker.unpack(bytes:):

extension Data {
    func unpack() -> ValueBox?
}

Unpackable stdlib types contains:

• Bool
• Double
• Float
• Int
• Int64
• String
• UInt
• UInt64

For other mixed types, you can alway use ValueBox instead.

enum ValueBox {
    case array([ValueBox])
    case binary(Binary)
    case bool(Bool)
    case dictionary([ValueBox: ValueBox])
    case double(Double)
    case `extension`(Extension)
    case float(Float)
    case int64(Int64)
    case `nil`
    case string(String)
    case uint64(UInt64)
}
