Nadylib\\Type
=============

[](#nadylibtype)

Introduction
------------

[](#introduction)

The type component of Nadylib is a ripped version of `Psl\Type` that was stripped down to be self-dependant and only has minimum requirements as well as working with PHP down to version 8.1. If you want a full framework, check out azjezz's awesome [PHP Standard Library](https://github.com/azjezz/psl).

`Nadylib\Type` provides a set of functions to ensure that a given value is of a specific type **at Runtime**. It aims to provide a solution for the [Parse, Don't Validate](https://lexi-lambda.github.io/blog/2019/11/05/parse-don-t-validate/) problem.

Usage
-----

[](#usage)

```
use Nadylib\Type;

$untrustedInput = $request->get('input');

// Turns a string-like value into a non-empty-string
$trustedInput = Type\nonEmptyString()->coerce($untrustedInput);

// Or assert that it's already a non-empty-string
$trustedInput = Type\nonEmptyString()->assert($untrustedInput);

// Or check if it's a non-empty-string
$isTrustworthy = Type\nonEmptyString()->matches($untrustedInput);
```

Every type provided by this component is an instance of `Type\TypeInterface`. This interface provides the following methods:

- `matches(mixed $value): $value is Tv` – Checks if the provided value is of the type.
- `assert(mixed $value): Tv` – Asserts that the provided value is of the type or throws an `AssertException` on failure.
- `coerce(mixed $value): Tv` – Coerces the provided value into the type or throws a `CoercionException` on failure.

Static Analysis
---------------

[](#static-analysis)

Your static analyzer should fully understand the types provided by this component if they support `@psalm-assert`. The only exception is `shape()` which would require a special component on the analyzers which is not available for `Nadylib\Type`. If you need this, use the [PHP Standard Library](https://github.com/azjezz/psl) instead.
