Types

type Request 

type Request interface {
	Call() *agent.Call
}

Request generates a Call that's sent to a Mesos agent. Subsequent invocations are expected to yield equivalent calls. Intended for use w/ non-streaming requests to an agent.

type RequestFunc 

type RequestFunc func() *agent.Call

RequestFunc is the functional adaptation of Request.

func NonStreaming 

func NonStreaming(c *agent.Call) RequestFunc

NonStreaming returns a RequestFunc that always generates the same Call.

func (RequestFunc) Call 

func (f RequestFunc) Call() *agent.Call

func (RequestFunc) Marshaler 

func (f RequestFunc) Marshaler() encoding.Marshaler

type RequestStreaming 

type RequestStreaming interface {
	Request
	IsStreaming()
}

RequestStreaming generates a Call that's send to a Mesos agent. Subsequent invocations MAY generate different Call objects. No more Call objects are expected once a nil is returned to signal the end of of the request stream.

type RequestStreamingFunc 

type RequestStreamingFunc func() *agent.Call

RequestStreamingFunc is the functional adaptation of RequestStreaming.

func Empty 

func Empty() RequestStreamingFunc

Empty generates a stream that always returns nil.

func FromChan 

func FromChan(ch <-chan *agent.Call) RequestStreamingFunc

FromChan returns a streaming request that fetches calls from the given channel until it closes. If a nil chan is specified then the returned func will always generate nil.

func Push 

func Push(r RequestStreaming, c ...*agent.Call) RequestStreamingFunc

Push prepends one or more calls onto a request stream. If no calls are given then the original stream is returned.

func (RequestStreamingFunc) Call 

func (f RequestStreamingFunc) Call() *agent.Call

func (RequestStreamingFunc) IsStreaming 

func (f RequestStreamingFunc) IsStreaming()

func (RequestStreamingFunc) Marshaler 

func (f RequestStreamingFunc) Marshaler() encoding.Marshaler

func (RequestStreamingFunc) Push 

func (f RequestStreamingFunc) Push(c ...*agent.Call) RequestStreamingFunc

type Sender 

type Sender interface {
	Send(context.Context, Request) (mesos.Response, error)
}

Send issues a Request to a Mesos agent and properly manages Call-specific mechanics.

type SenderFunc 

type SenderFunc func(context.Context, Request) (mesos.Response, error)

SenderFunc is the functional adaptation of the Sender interface

func IgnoreResponse 

func IgnoreResponse(s Sender) SenderFunc

IgnoreResponse generates a sender that closes any non-nil response received by Mesos.

func (SenderFunc) Send 

func (f SenderFunc) Send(ctx context.Context, r Request) (mesos.Response, error)

Send implements the Sender interface for SenderFunc
