Package transport

type Connection ¶

Connection is the interface defining a data connection, such as a socket or a mocked implementation.

type Connection interface {
    io.ReadWriteCloser
    CloseRead() error
    CloseWrite() error
    File() (*os.File, error)
}

type DevNullTransport ¶

DevNullTransport is a transport that will:

For reads: return either closed or EOF for as appropriate. For writers: return either closed or throw away the write as appropriate.

The DevNullTransport is used as the container logging transport when stdio access is denied. It is also used for non-terminal external processes (aka a process run in the UVM) when stdio access is denied.

type DevNullTransport struct{}

func (*DevNullTransport) Dial ¶

func (t *DevNullTransport) Dial(fd uint32) (Connection, error)

type Transport ¶

Transport is the interface defining a method of transporting data in a connection-like way. Examples of a Transport implementation could be:

-Hyper-V socket transport
-TCP/IP socket transport
-Mocked-out local transport

type Transport interface {
    // Dial takes a port number and returns a connected connection.
    Dial(port uint32) (Connection, error)
}

type VsockTransport ¶

VsockTransport is an implementation of Transport which uses vsock sockets.

type VsockTransport struct{}

func (*VsockTransport) Dial ¶

func (t *VsockTransport) Dial(port uint32) (Connection, error)

Dial accepts a vsock socket port number as configuration, and returns an unconnected VsockConnection struct.
