InheritanceYiisoft\Validator\RuleHandlerResolver\RuleHandlerContainer
ImplementsYiisoft\Validator\RuleHandlerResolverInterface

An implementation for {@see RuleHandlerResolverInterface} acting as a wrapper over dependency injection container ({@see ContainerInterface}) throwing more specific exceptions and executing additional checks during resolving a rule handler name to make sure that if a handler was found, then it's indeed a valid handler to work with.

To use it, make sure to change config.php like so:

use Yiisoft\Validator\RuleHandlerResolverInterface;
use Yiisoft\Validator\RuleHandlerResolver\RuleHandlerContainer;

[
    RuleHandlerResolverInterface::class => RuleHandlerContainer::class,
];

If you don't need DI container, {@see \Yiisoft\Validator\RuleHandlerResolver\SimpleRuleHandlerContainer} can be used instead. It's enabled by default, you don't need to additionally configure anything.
