Implement `Encode` and `Decode` for non-empty tuple types?

[repnop]

I've been messing around with a library for some work stuff and had an interesting idea that would utilize tuple types, though they would need the Encode and Decode impls for this to work. my thought is that the tuples would be encoded as a SEQUENCE type, similar to arrays and Vecs, but allowing for heterogeneous types in the sequence. thoughts? only complication I think would be perhaps in the decoding step since right now the decode_sequence_of API expects a single type and the decode_sequence seems somewhat complicated for something like this (and I didn't quite understand exactly what the purpose of some of the parameters and args was).

It would need to use decode_sequence, because as you said, heterogenous types. It would also need to still have field information for codecs like JER, which I think is the bigger issue, since if you need field names, why have a tuple? I think maybe one possibility is for small fixed inner sequence. I think this would be supplanted if anonymous struct language feature was ever stabilised.

#[derive(AsnType)]
struct Foo {
    #[rasn(sequence(field_1, field_2))]
    inner: (u32, u32),
}
