Build a CacheKey, ensuring it's valid for Memcached

https://github.com/memcached/memcached/blob/master/doc/protocol.txt#L41

Currently the length limit of a key is set at 250 characters (of course,
normally clients wouldn't need to use such long keys); the key must not
include control characters or whitespace.

cacheKeyThrow :: (MonadIO m, HasCallStack) => Text -> m CacheKey Source #

Build a CacheKey and throw if invalid
