Features
--------

[](#features)

TypeGuard can validate:

- Scalar types: `string`, `integer`, etc.:

```
(new TypeGuard('string'))->match('foo'); // => true
```

- Object types: `ArrayAccess`, `stdClass`, etc.:

```
(new TypeGuard('stdClass'))->match(new stdClass()); // => true
```

- Union types: `string|integer`:

```
$guard = new TypeGuard('string|integer');
$guard->match('foo'); // => true
$guard->match(1); // => true
```

- Intersection types: `ArrayAccess&Countable`:

```
(new TypeGuard('ArrayAccess&Countable'))->match(new ArrayIterator()); // => true
```

- Optional types: `?string`:

```
(new TypeGuard('?string'))->match(null); // => true
```
