Switon's validation layer for constraint attributes, typed input conversion, and localized error messages.

Highlights
----------

[](#highlights)

- **Constraint attributes:** `Required`, `Length`, `Email`, and related attributes validate fields directly.
- **Typed values:** `Type` and `Defaults` can fill and cast values during validation.
- **Validation flow:** one-shot and manual validation are both supported.
- **Localized messages:** template files provide per-locale fallback messages and labels.

Installation
------------

[](#installation)

```
composer require switon/validation
```
