In C#, Enums are just semantic ints (or other integer-like types). In Rust however, they're (afaict) discriminated unions.
I'm building a set of microservices that require communication over websockets. I'm curious what's the best way to represent the semantic value of the numeric value (e.g. the C# enum) when it comes to deserializing the message in Rust?
For context:
public enum DispatchAction
{
Hello, // 0
Identify, // 1
Ready, // 2
Disconnecting // 3
}
main cobalt

If you're using serde, the serde_repr crate has a thing for that: https://serde.rs/enum-number.html

serde seems to be bog standard, and some other libs I'm using use it so I'll definitely be doing that, thanks!
Oh huh I didn't even know you could do this with enum variants
main cobalt
Formally, you're setting the value of the discriminant, and IIRC you can do that for variants that aren't dataless too
(though this crate won't work with them anyway)
