Converting Class objects into Data to serialise as .dat file

Using Swift

I debugged my test and found one of the major contributor to slowness in the Codable based serialiser:

class MyEncoder: Encoder {
    ...
    func encode(_ value: Float) {
        ...
    }
    func encode<T: Encodable>(_ val: T) {
        try! val.encode(to: self)
    }
    ....

    private struct KeyedContainer<Key: CodingKey>: KeyedEncodingContainerProtocol {
        var myEncoder: MyEncoder
        
        func encode<T: Encodable>(_ value: T, forKey key: Key) {
            myEncoder.encode(value)
        }
        ...
    }
    ...
}

Stepping through the line "myEncoder.encode(value)" where the value passed was Float, the resulting "encode" method being called was not the specialised "encode(_ value: Float)" but generic "encode<T: Encodable>(_ val: T)" (why it is this way is discussed here). I put the workaround and interestingly that one change sped the serialised 10 times, so now my codable based serialised is just 10x slower than the manual serialiser.
