The idiomaticity and power of kotlins `require` for spring boot rest API's. :ok_hand:

please, don’t get this the wrong, I hope I don’t sound rude, but what is your goal here? from the examples, what you want to do seems to me to be validation, why creating a new library rather than using what already exists?

java provides `javax.validation` specification and `hibernate-validator` implements them quite nicely, especially in an api context since the path of the violating field can easily be described. and you also get all the errors in one call

the other example you provide on authorization is probably even less realistic, authorization is not a prerequisite but a complex flow. just think how to handle password base, flow base, sso, oauth, openid and all stuff that spring security already does with `require` seems a bit overwhelming to me
