There is a Scala 3 build failure that is failing the build (maybe among other things).

@jdegoes The way this is modeled rn makes it impossible to to analyse if it is single or multi value. This might make it hard to generate docs etc. from endpoints. What do you think about adding a field queryStyle to the codec or a new annotation?
Both could also contain information about how multi values should be rendered. ?a=1&a=2 vs ?a=1,2 vs ?a=1|2 or maybe even others.
That would likely be more important for clients, to be compliant with their requirements.

@987Nabil The way this is modeled rn makes it impossible to to analyse if it is single or multi value.

How about QueryParamHint which could be QueryParamHint.Zero, QueryParamHint.One, QueryParamHint.Many, QueryParamHint.Any. Then the constructors can feed the hint in, and the documentation generation can use the hint.

Most code doesn't need to know about that, it's only really for doc or client generation.

@ekhov I think you get the idea. Try what @jdegoes suggested and adjust the idea if needed. What is important is, that we can find intend in the data.

@jdegoes Do I get it correctly that you want this hint to be added as a Query parameter? And at the moment we will use only One(single value codecs) and Many(for multi value)?
