Lookup

final case class Lookup[-Key, -Environment, +Error, +Value](lookup: (Key) => ZIO[Environment, Error, Value]) extends (Key) => ZIO[Environment, Error, Value] with Product with Serializable

A Lookup represents a lookup function that, given a key of type Key, can return a ZIO effect that will either produce a value of type Value or fail with an error of type Error using an environment of type Environment.

You can think of a Lookup as an effectual function that computes a value given a key. Given any effectual function you can convert it to a lookup function for a cache by using the Lookup constructor.
