🚀 New issue to wemake-services/django-modern-rest by @sobolevn
📝 Add `Parser.validate` method to perform import-time checks (#1304)


While working on #1275, I realized that proposed OctetStreamParser is kinda unique,
because it must not contain Body[...] near FileMetadata[...] defintions.
Why? Because it only accepts a single stream of bytes, there can't be a body nearby.

So, what should we do for similar cases? I propose adding validate method to the Parser class, empty by default. It would be similar to ComponentParser.validate method. And then call it in validation process.

This test parser should check that it only works on endpoints with FileMetadata and no Body.
