Types

type Proxy 

type Proxy struct {
	// contains filtered or unexported fields
}

Proxy controls copying data between two proxyConnections. Proxy takes ownership over the two connections and is responsible for cleaning up their resources (i.e. calling their Close method). Proxy(s) all run internal to the sandbox on the supervisor context.

func NewProxy 

func NewProxy(pair ProxyPair, cid string) *Proxy

NewProxy returns a new Proxy.

func (*Proxy) AddCleanup 

func (pf *Proxy) AddCleanup(cu func())

AddCleanup adds a cleanup to this Proxy's cleanup.

func (*Proxy) Close 

func (pf *Proxy) Close()

Close cleans up the resources in this Proxy and blocks until all resources are cleaned up and their goroutines exit.

func (*Proxy) Start 

func (pf *Proxy) Start(ctx context.Context)

Start starts the proxy. On error on either end, the proxy cleans itself up by stopping both connections.

type ProxyPair 

type ProxyPair struct {
	To   proxyConn
	From proxyConn
}

ProxyPair wraps the to/from arguments for NewProxy so that the user explicitly labels to/from.
