[darthf1]

Changes

With this change, Symfony's cache adapter is used instead of the one provided by this library.

References

From @evansims comment in #108 (comment):

Symfony has its own Psr16Adapter but for the life of me, I could not get it to work with the TraceableAdapter type Symfony is >using. Someone smarter than I might be able to figure that one out, in which case a PR would be most welcome.

Hey, @darthf1, thanks for this! 👋 I tried going this Psr16Adapter route during the previous commit but I kept encountering exceptions around Psr16Adapter being unable to accept instances of Symfony\Component\Cache\Adapter\TraceableAdapter, and I could never figure out a workaround for it. I'll give this a try next week and see if this works better!

[evansims]

Looks good to me! No idea why this was throwing an error for me before but all appears well now, so all the better! Thanks for your contribution!

[darthf1]

Great! Do you want me to remove the helper and the related test as well as they're not used anymore?

[evansims]

That would be great if you don't mind @darthf1

[darthf1]

@evansims no problem, done

Appreciate it! Just need to fix an issue with our status checks on the repo before I can merge, hang tight.
