A Rust library providing struct validation via a custom derive macro, inspired by marshmallow and Django validators. It offers built-in rules like email, url, length, and range, plus custom validation functions, returning structured validation errors.
Use cases
- validate user signup form data in rust
- validate email and url fields on structs
- custom field validation rules in rust
- validate nested structs and collections
- validate deserialized serde input
When to choose
- you need declarative, attribute-based validation on rust structs
- you want built-in validators like email, url, length, and range
- you need structured, serializable validation errors keyed by field
When to avoid
- you need async or database-backed validation out of the box
- your project is not written in rust
