trait Cache extends AnyRef
A Cache maintains an internal state with a mapping from requests to Refs
that will contain the result of those requests when they are executed. This
is used internally by the library to provide deduplication and caching of
requests.

def
get[E, A](request: Request[E, A]): IO[Unit, Ref[Option[Either[E, A]]]]
Looks up a request in the cache, failing with the unit value if the request is not in the cache, succeeding with
Ref(None)if the request is in the cache but has not been executed yet, orRef(Some(value))if the request has been executed. -

def
put[E, A](request: Request[E, A], result: Ref[Option[Either[E, A]]]): UIO[Unit]
Inserts a request and a
Refthat will contain the result of the request when it is executed into the cache.
