Support serde_valid

[ya7010]

Thanks for the great crate!!

Hi. I am the author of serde_valid.

schemars provides macros that are written equivalent to validator, but is it possible to support serde_valid?

serde_valid has the following advantages over validator:

• Based on JsonSchema
• Support for struct and enum
• More friendly and simple interface

I am considering making attributes support for validator (and serde_valid ) into features.

I can also help with implementation, are you interested?

This would be great to have since validator appears to be unable to support validation during deserialization (see here) and it's super easy to forget calling validate. Is there any news on this issue?

I also would love to see this and can also help with implementation.
