| # 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. | ||
