It’s already documented at:
It works fine but not very idiomatic, I’d personally do it like (well I generally have the fallback built into the cache rather than on each call, but ignoring that part):
def get_cached_thing!(slug) do
Cachex.get(:my_cache, slug, fallback: fn(slug) ->
Repo.get_by!(Mything, slug: slug)
end)
|> case do
{:error, _} -> nil # It's not common to return error strings, rather you'd probably want an error tuple
{success, value} when success in [:ok, :loaded] -> value
end
end
Or maybe using ok/error tuples, whichever.
