This includes things like its IP address, identity, metadata (name, namespace, app, version, etc), and whether it has a waypoint proxy associated.

The `Service` aims to represent everything about a service (generally a `Service` or `ServiceEntry`).
This includes things like its IP addresses, ports and an associated waypoint proxy if it has one.

### Authorization Type

**"Dependency Injection"** means, in programming, that there is a way for your code (in this case, your *path operation functions*) to declare things that it requires to work and use: "dependencies".

And then, that system (in this case **FastAPI**) will take care of doing whatever is needed to provide your code with those needed dependencies ("inject" the dependencies).

This is very useful when you need to:

                mavenRepo.module("thing", "lib1", "2.0-SNAPSHOT").dependsOn(dep).publish()
            }
        }

        @Override
        void publishNewSnapshot(AbstractIntegrationSpec owner) {
            owner.with {
                def dep = mavenRepo.module("thing", "lib2", "4.1").publish()
                def module = mavenRepo.module("thing", "lib1", "2.0-SNAPSHOT").dependsOn(dep)

            }
            extensions.add('things', SomeThing)
            things {
                letter = 'a'
                withLetter('b')
            }
            assert things.letter == Letter.B
            things.other('ABC')
            assert things.letter == Letter.A
            things.other(Letter.C)
            assert things.letter == Letter.C
            things.other('A', 'ignore')
