Overview

Package echofx provides better integration for Fx for services implementing or calling Echo.

Clients

If you are making requests to Echo, use the Client function to inject a Echo client into your container.

fx.Provide(echofx.Client("..."))

Servers

If you are implementing Echo, provide a echoserver.Interface into the container and use the Server function.

Given,

func NewEchoHandler() echoserver.Interface

You can do the following to have the procedures of Echo made available to an Fx application.

fx.Provide(
	NewEchoHandler,
	echofx.Server(),
)

Functions

func Client

func Client(name string, opts ...thrift.ClientOption) interface{}

Client provides a Echo client to an Fx application using the given name for routing.

fx.Provide(
	echofx.Client("..."),
	newHandler,
)

func Server

func Server(opts ...thrift.RegisterOption) interface{}

Server provides procedures for Echo to an Fx application. It expects a echofx.Interface to be present in the container.

fx.Provide(
	func(h *MyEchoHandler) echoserver.Interface {
		return h
	},
	echofx.Server(),
)

Types

type Params

type Params struct {
	fx.In

	Provider    yarpc.ClientConfig
	Restriction restriction.Checker `optional:"true"`
}

Params defines the dependencies for the Echo client.

type Result

type Result struct {
	fx.Out

	Client echoclient.Interface
}

Result defines the output of the Echo client module. It provides a Echo client to an Fx application.

type ServerParams

type ServerParams struct {
	fx.In

	Handler echoserver.Interface
}

ServerParams defines the dependencies for the Echo server.

type ServerResult

type ServerResult struct {
	fx.Out

	Procedures []transport.Procedure `group:"yarpcfx"`
}

ServerResult defines the output of Echo server module. It provides the procedures of a Echo handler to an Fx application.

The procedures are provided to the "yarpcfx" value group. Dig 1.2 or newer must be used for this feature to work.
