Decoder
Usage
Decoding any values
You can use decode() and a match to filter values. This function will hand you the values after finishing decoding
process.
Decoding desired values
You can use decode_*(). However, please note that: if an un-expected value is detected, the whole decoding operation might be broken.
It’s because those functions just decode the header of a value, and stop if not matched. So at that point, data stream is already broken.
In contrast, with decode(), when you expect an Object but get a List, you can still
continue decoding next values.
