-## Struct level validations
-
-Validations can also be registered at the `struct` level when field level validations
-don't make much sense. This can also be used to solve cross-field validation elegantly.
-Additionally, it can be combined with tag validations. Struct Level validations run after
-the structs tag validations.
-
-### Example requests
-
-```shell
-# Validation errors are generated for struct tags as well as at the struct level
-$ curl -s -X POST http://localhost:8085/user \
-	-H 'content-type: application/json' \
-	-d '{}' | jq
-{
-  "error": "Key: 'User.Email' Error:Field validation for 'Email' failed on the 'required' tag\nKey: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
-  "message": "User validation failed!"
-}
-
-# Validation fails at the struct level because neither first name nor last name are present
-$ curl -s -X POST http://localhost:8085/user \
-    -H 'content-type: application/json' \
-	-d '{"email": "george@vandaley.com"}' | jq
-{
-  "error": "Key: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
-  "message": "User validation failed!"
-}
-
-# No validation errors when either first name or last name is present
-$ curl -X POST http://localhost:8085/user \
-    -H 'content-type: application/json' \
-	-d '{"fname": "George", "email": "george@vandaley.com"}'
-{"message":"User validation successful."}
-
-$ curl -X POST http://localhost:8085/user \
