PSR-6 Cache Utilities
=====================

[](#psr-6-cache-utilities)

[![Quality Assurance](https://github.com/php-fig/cache-util/workflows/Quality%20Assurance/badge.svg)](https://github.com/php-fig/cache-util/workflows/Quality%20Assurance/badge.svg)

This package contains a series of traits and base classes to cover the common, boilerplate portions of implementing a PSR-6-compliant cache library.

This package also provides a basic in-memory-only PSR-6 implementation. While not useful for actual use, it serves as a demo-implementation as well as a debugging tool.

This package does not, and will not, provide a complete production-ready PSR-6 implementation. If you are looking for a PSR-6 implementation, consult your friendly local Packagist.org server.
