Compile time only

[backuitist]

We have this situation where different team with different taste (one like circe-generic, another like circe-derivation) need to share circe codecs.
Having circe-derivation compile-time only makes it possible to define those codecs using circe-derivation without commiting (pulling one transitively) to either generic or derivation.

Thanks, @backuitist!

[travisbrown]

I can go ahead and publish a new milestone tomorrow if that'd be useful, @backuitist?

[neko-kai]

Eh, somewhat conflicts with our usage here (summoning circe-derivation codecs with implicit macro) https://github.com/pshirshov/izumi-r2/blob/develop/idealingua/idealingua-runtime-rpc-circe/src/main/scala/com/github/pshirshov/izumi/idealingua/runtime/circe/IRTWithCirce.scala#L8

[backuitist]

@travisbrown yes, a release would be great! Thanks!

@Kaishh I don't see how this change impacts your code?

[neko-kai]

@backuitist It doesn't, but merging similar code upstream would mean creating DerivedDecoder, DerivedEncoder, etc. runtime classes which may possibly conflict with your usecase

[travisbrown]

@Kaishh We could have a new module named circe-derivation-extras (or something better), with the contract being that everything in circe-derivation can be used as a compile-time only dependency, while circe-derivation-extras would provide a runtime API with things like a WithCirceCodec trait.

[backuitist]

@Kaishh I don't understand what you mean by "merging similar code upstream"? What is upstream?
Why would this mean creating DerivedDecoder classes?
