/**
 * Used to define rules for validation of nested structures:
 *
 * - For one-to-one relation, using `Nested` rule is enough.
 * - One-to-many and many-to-many relations require pairing with {@see Each} rule.
 *
 * An example with blog post:
 *
 * ```php
 * $rules = [
 *     new Nested([
 *         'title' => [new HasLength(max: 255)],
 *          // One-to-one relation
 *         'author' => new Nested([
 *             'name' => [new HasLength(min: 1)],
 *         ]),
 *         // One-to-many relation
 *         'files' => new Each(new Nested([
 *             'url' => [new Url()],
 *         ])),
 *     ]);
 * ];
 * ```
 *
 * There is an alternative way to write this using dot notation and shortcuts:
 *
 * ```php
 * $rules = [
 *     new Nested([
 *         'title' => [new HasLength(max: 255)],
 *         'author.name' => [new HasLength(min: 1)],
 *         'files.*.url' => [new Url()],
 *     ]);
 * ];
 * ```
 *
 * For more examples please refer to the guide.
 *
 * It's also possible to use DTO objects with PHP attributes, see {@see ObjectDataSet} documentation and guide for
 * details.
 *
 * Supports propagation of options (see {@see PropagateOptionsHelper::propagate()} for supported options and
 * requirements).
 *
 * @see NestedHandler Corresponding handler performing the actual validation.

		0 ignored issues – show Bug introduced 2022-08-01 11:18 UTC by Report Bug Copy Issue Report This use statement conflicts with another class in this namespace, `Yiisoft\Validator\Rule\count`. Consider defining an alias. Let?s assume that you have a directory layout like this: . \|-- OtherDir \| \|-- Bar.php \| `-- Foo.php `-- SomeDir `-- Foo.php and let?s assume the following content of `Bar.php`: // Bar.php namespace OtherDir; use SomeDir\Foo; // This now conflicts the class OtherDir\Foo If both files `OtherDir/Foo.php` and `SomeDir/Foo.php` are loaded in the same runtime, you will see a PHP error such as the following: PHP Fatal error: Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php However, as `OtherDir/Foo.php` does not necessarily have to be loaded and the error is only triggered if it is loaded before `OtherDir/Bar.php`, this problem might go unnoticed for a while. In order to prevent this error from surfacing, you must import the namespace with a different alias: // Bar.php namespace OtherDir; use SomeDir\Foo as SomeDirFoo; // There is no conflict anymore.

40		* Used to define rules for validation of nested structures:
41		*
42		* - For one-to-one relation, using `Nested` rule is enough.
43		* - One-to-many and many-to-many relations require pairing with {@see Each} rule.
44		*
45		* An example with blog post:
46		*
47		* ```php
48		* $rules = [
49		* new Nested([
50		* 'title' => [new HasLength(max: 255)],
51		* // One-to-one relation
52		* 'author' => new Nested([
53		* 'name' => [new HasLength(min: 1)],
54		* ]),
55		* // One-to-many relation
56		* 'files' => new Each(new Nested([
57		* 'url' => [new Url()],
58		* ])),
59		* ]);
60		* ];
61		* ```
62		*
63		* There is an alternative way to write this using dot notation and shortcuts:
64		*
65		* ```php
66		* $rules = [
67		* new Nested([
68		* 'title' => [new HasLength(max: 255)],
69		* 'author.name' => [new HasLength(min: 1)],
70		* 'files.*.url' => [new Url()],
71		* ]);
72		* ];
73		* ```
74		*
75	26	* For more examples please refer to the guide.
76		*
77		* It's also possible to use DTO objects with PHP attributes, see {@see ObjectDataSet} documentation and guide for
78		* details.
79		*
80		* Supports propagation of options (see {@see PropagateOptionsHelper::propagate()} for supported options and
81		* requirements).
82		*
83		* @see NestedHandler Corresponding handler performing the actual validation.
