Expected behaviour

I'm writing a kafka test follow below example, from the link: https://docs.pact.io/implementation_guides/go/docs/messages#provider-producer

func TestV3MessageProvider(t *testing.T) {
    var user *User

    verifier := MessageVerifier{}

    // 1. Map test descriptions to message producer functions (handlers)
    functionMappings := MessageHandlers{
        "a user event": func([]ProviderStateV3) (interface{}, error) {
            if user != nil {
                return user, nil
            } else {
                return ProviderStateV3Response{
                    "message": "not found",
                }, nil
            }
        },
    }

  // 2. Setup any required states for the handlers
    stateMappings := StateHandlers{
        "User with id 127 exists": func(setup bool, s ProviderStateV3) (ProviderStateV3Response, error) {
            if setup {
                user = &User{
                    ID:       127,
                    Name:     "Billy",
                    Date:     "2020-01-01",
                    LastName: "Sampson",
                }
            }

            return ProviderStateV3Response{"id": user.ID}, nil
        },
    }

    // V3. erify the Provider with local Pact Files
    verifier.Verify(t, VerifyMessageRequest{
        VerifyRequest: VerifyRequest{
            PactFiles:     []string{filepath.ToSlash(fmt.Sprintf("%s/V3MessageConsumer-V3MessageProvider.json", pactDir))},
            StateHandlers: stateMappings,
        },
        MessageHandlers: functionMappings,
    })
}

but I cannot find the definition of MessageVerifier and ProviderStateV3Response. I searched the pact - go project through the code - search function and found that no code defined MessageVerifier. Is there something wrong?

Actual behaviour

Please help me provide an example of testing Kafka in Golang.

Steps to reproduce

Provide a repository, gist or reproducable code snippet so that we can test the problem. You may also want to adapt one of the examples in the repository to demonstrate the problem.

Relevent log files

Please ensure you set logging to DEBUG and attach any relevant log files here (or link from a gist).

Looks like the docs have drifted, here is an example: https://github.com/pact-foundation/pact-go/blob/master/examples/consumer_v3_test.go#L92

so cool. it works now
