RedisUtil ​

Raxos\Cache\Redis\RedisUtil is a small static helper that turns a RedisException from the extension into a typed RedisErrorException. Every command group trait, as well as RedisCache and RedisTaggedCache, routes its Redis calls through this helper. See error handling for the exception hierarchy.

php
final class RedisUtil

Methods ​

wrap ​

php
public static function wrap(callable $fn, mixed ...$arguments): mixed

Calls $fn with the given arguments and returns its result. When the callable throws a RedisException, it is caught and rethrown as a RedisErrorException, which implements RedisCacheExceptionInterface.

Example ​

Use wrap() when you extend RedisCache with additional raw Redis calls that should follow the same error convention.

php
<?php
declare(strict_types=1);

use Raxos\Cache\Redis\{RedisCache, RedisUtil};

final class ExtendedRedisCache extends RedisCache
{
    public function llen(string $key): int
    {
        return RedisUtil::wrap($this->connection->lLen(...), $key);
    }
}
