As in title.

I agree that does make sense to have. I'll look into it.

@rofrol I have a working implementation in #2. Do you wanna have a look?

[rofrol]

Right now I am using

#[serde(deny_unknown_fields)]

But If you don't use serde and want to check two jsons, it will be very valuable.

@rofrol This is done and released as version 0.2.0 😄
