Hi,
thank you for your project, it's exactly what i'm looking for some time 💯
I'm also developing rest API using Go and Echo and we use OpenAPI to document ours apis.
In my apis, i'm a huge fan & user of package go-playground/validator to validate data i received (like min string length , etc...).
It will be awesome if you could support this in schema structure generation. What do you think ? Do you need help to do that ?
