Overview

Package transport is an interface for synchronous connection based communication

Index

type Client

type Client interface {
	Socket
}

type DialOption

type DialOption func(*DialOptions)

func WithStream

func WithStream() DialOption

Indicates whether this is a streaming connection

func WithTimeout

func WithTimeout(d time.Duration) DialOption

Timeout used when dialling the remote side

type DialOptions

type DialOptions struct {
	// Tells the transport this is a streaming connection with
	// multiple calls to send/recv and that send may not even be called
	Stream bool
	// Timeout for dialing
	Timeout time.Duration

	// Other options for implementations of the interface
	// can be stored in a context
	Context context.Context
}

type ListenOption

type ListenOption func(*ListenOptions)

type ListenOptions

type ListenOptions struct {

	// Other options for implementations of the interface
	// can be stored in a context
	Context context.Context
}

type Listener

type Listener interface {
	Addr() string
	Close() error
	Accept(func(Socket)) error
}

type Message

type Message struct {
	Header map[string]string
	Body   []byte
}

type Option

type Option func(*Options)

func Addrs

func Addrs(addrs ...string) Option

Addrs to use for transport

func Codec

func Codec(c codec.Marshaler) Option

Codec sets the codec used for encoding where the transport does not support message headers

func Secure

func Secure(b bool) Option

Use secure communication. If TLSConfig is not specified we use InsecureSkipVerify and generate a self signed cert

func TLSConfig

func TLSConfig(t *tls.Config) Option

TLSConfig to be used for the transport.

func Timeout

func Timeout(t time.Duration) Option

Timeout sets the timeout for Send/Recv execution

type Options

type Options struct {
	// Addrs is the list of intermediary addresses to connect to
	Addrs []string
	// Codec is the codec interface to use where headers are not supported
	// by the transport and the entire payload must be encoded
	Codec codec.Marshaler
	// Secure tells the transport to secure the connection.
	// In the case TLSConfig is not specified best effort self-signed
	// certs should be used
	Secure bool
	// TLSConfig to secure the connection. The assumption is that this
	// is mTLS keypair
	TLSConfig *tls.Config
	// Timeout sets the timeout for Send/Recv
	Timeout time.Duration
	// Other options for implementations of the interface
	// can be stored in a context
	Context context.Context
}

type Socket

type Socket interface {
	Recv(*Message) error
	Send(*Message) error
	Close() error
	Local() string
	Remote() string
}

type Transport

type Transport interface {
	Init(...Option) error
	Options() Options
	Dial(addr string, opts ...DialOption) (Client, error)
	Listen(addr string, opts ...ListenOption) (Listener, error)
	String() string
}

Transport is an interface which is used for communication between services. It uses connection based socket send/recv semantics and has various implementations; http, grpc, quic.

var (
	DefaultTransport Transport = newHTTPTransport()

	DefaultDialTimeout = time.Second * 5
)

func NewTransport

func NewTransport(opts ...Option) Transport
