example for a custom serialization and deserialization

[Hugo-Trentesaux]

Where could I find an example on how to build a custom serializer / deserializer with bincode for my structure? Or do I have to implement my own functions to replace bincode::serialize and bincode::deserialize?

@Hugo-Trentesaux I'm not sure I understand what you are asking. Could you give a code example of what you are trying to accomplish?

For example, I have an enum that I know can only take two values (a hash or a signature). I would like to store the variant on only 1 byte instead of 8. For now, I'm using two option, but that's does not represent what I want (I never have both hash and signature).

I don't believe there is anything specific to bincode involved in that. You would write a custom Serialize/Deserialize implementation for your type, and if you ran bincode::serialize on it then it would be invoked appropriately.

https://github.com/servo/ipc-channel/blob/master/src/ipc.rs#L802-L822 is not a super clear example, but it does show a custom serialization that is used with the bincode serializer.
