View Source Cachex.Query (Cachex v3.6.0)
Utility module based around creation of cache queries.
Queries are essentially just some minor convenience wrappers around the
internal match specification used by ETS. This module is exposed to make
it easier to query a cache (via Cachex.stream/3) without having to take
care of filtering for expirations by hand.
Note that there is almost no validation in here, so test thoroughly and store compile-time versions of your queries when possible (as performance is not taken into account inside this module; it can be slow to generate).
