Parsing schemas for code generation

[TomzBench]

This crate has a strong focus on validation of data in a performant way. Another great use case for json schemas is code generation. I am currently parsing json schemas for generating code inside of a proc macro. So I would like to parse a schema and iterate over objects and generate structs, for example. Is that possible with this crate?

I have the same idea. Have you started some experiments? I think it is doable, if we define an appropriate mapping for each validation node to some intermediate data representation from which the code is derived.

I am trying to understand how quicktype or the swagger generator are accumulating information...

I'm working on it for quite some time now. At the beginning I've tried to use same code or ideas, but the way schema validation is done is quite different from how a generator would work

@goto40 i ended up using @scalar/openapi-parser to generate an intermediate step which rust can parse for the proc macro. the javascript ecosystem is just way better for openapi spec. i output a yaml file w/ a flatten structure w/ all the data types discovered, w/ extra metadata containing codegeneration constraints for my use case. then the rust code just reads the preparsed artifact which is tailored to my needs. rust side becomes trivial on the parser requirments, and focuses more on codegen only.
