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.

const GetMetadataFuncName = "GetPluginMetadata"

GetMetadataFuncName is the name of the function in the plugin to return PluginMetadata.

Variables

View Source 
var (
	// ErrNoClue is for the situation that existing information is not enough to make a decision. For example, Router may return this error when there is no suitable route.
	ErrNoClue = errors.New("not enough information for making a decision")
)

Functions

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.

func LoadPlugins 

func LoadPlugins() error

LoadPlugins loads all possible plugins in the 'plugin' directory.

func RegisterConfigLoader 

func RegisterConfigLoader(format *ConfigFormat) error

RegisterConfigLoader add a new ConfigLoader.

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.
