Overview

Package core provides an entry point to use V2Ray core functionalities.

V2Ray makes it possible to accept incoming network connections with certain protocol, process the data, and send them through another connection with the same or a difference protocol on demand.

It may be configured to work with multiple protocols at the same time, and uses the internal router to tunnel through different inbound and outbound connections.

Functions

func AddInboundHandler 

func AddInboundHandler(server *Instance, config *InboundHandlerConfig) error

func AddOutboundHandler 

func AddOutboundHandler(server *Instance, config *OutboundHandlerConfig) error

func CreateObject 

func CreateObject(v *Instance, config interface{}) (interface{}, error)

CreateObject creates a new object based on the given V2Ray instance and config. The V2Ray instance may be nil.

func Dial 

func Dial(ctx context.Context, v *Instance, dest net.Destination) (net.Conn, error)

Dial provides an easy way for upstream caller to create net.Conn through V2Ray. It dispatches the request to the given destination by the given V2Ray instance. Since it is under a proxy context, the LocalAddr() and RemoteAddr() in returned net.Conn will not show real addresses being used for communication.

v2ray:api:stable

func DialUDP 

func DialUDP(ctx context.Context, v *Instance) (net.PacketConn, error)

DialUDP provides a way to exchange UDP packets through V2Ray instance to remote servers. Since it is under a proxy context, the LocalAddr() in returned PacketConn will not show the real address.

TODO: SetDeadline() / SetReadDeadline() / SetWriteDeadline() are not implemented.

v2ray:api:beta

func RegisterConfigLoader 

func RegisterConfigLoader(format *ConfigFormat) error

RegisterConfigLoader add a new ConfigLoader.

func ServerType 

func ServerType() interface{}

ServerType returns the type of the server.

func Version 

func Version() string

Version returns V2Ray's version as a string, in the form of "x.y.z" where x, y and z are numbers. ".z" part may be omitted in regular releases.

func VersionStatement 

func VersionStatement() []string

VersionStatement returns a list of strings representing the full version info.

Types

type Annotation 

type Annotation struct {
	// API is for types or functions that can be used in other libs. Possible values are:
	//
	// * v2ray:api:beta for types or functions that are ready for use, but maybe changed in the future.
	// * v2ray:api:stable for types or functions with guarantee of backward compatibility.
	// * v2ray:api:deprecated for types or functions that should not be used anymore.
	//
	// Types or functions without api annotation should not be used externally.
