turandot VS ozzo-validation

I created Turandot, Candice, Reposure, Knap, CNCK, QCR, multusctl, and a whole bunch of dependent libraries, and also participate in a bunch of other K8s-related projects.

go-ozzo/ozzo-validation

https://github.com/go-ozzo/ozzo-validation Seems to do what I need but likely will need some convoluted reflection to build out the rules. Also likely some custom rules to be written which is okay since it's a one time cost and reuse in the expressions.

Personally I use ozzo validation: https://github.com/go-ozzo/ozzo-validation

This looks useful, but what differentiates it from something like https://github.com/go-ozzo/ozzo-validation ? Why would I use Valgo over something battle tested that follows a very similar pattern?

This is where it gets spicy: I just don't get at all who ever though this struct-tag based validation library was a good idea https://github.com/go-playground/validator - and yet it's the most mainstream one. Try to implement your own type, you're up to register some global validation tag and repeat it every time you're using that type. I'm grateful https://github.com/go-ozzo/ozzo-validation exists, that's what I use. But it's still way behind the other things I mention, where in general, it's simply not possible to pass around an invalid struct - because it can't be built if it's invalid in the first place.

Gin comes with built-in "validation", while Echo recommends the same validator. I am also not a fan of magic struct tags, so I would probably prefer either writing my own or using something like ozzo.

Does https://github.com/go-ozzo/ozzo-validation meet your requirements?
