Use this property in the request classes to stop the validation of the whole request attributes

Use this property in the request classes to stop the validation of the whole request attributes.

Hint Direct

This is different from Bail rule that stops the validation for just a single attribute if one of its rules doesn't validate.

/**
* Indicated if the validator should stop
 * the entire validation once a single
 * rule failure has occurred.
 */
protected $stopOnFirstFailure = true;
