Functions

func CallNoData

func CallNoData(ctx context.Context, caller Caller, call *executor.Call) error

CallNoData is a convenience func that executes the given Call using the provided Caller and always drops the response data.

func Executor

func Executor(id string) executor.CallOpt

Executor sets a executor.Call's ExecutorID

func Framework

func Framework(id string) executor.CallOpt

Framework sets a executor.Call's FrameworkID

func Heartbeat

func Heartbeat() *executor.Call

Heartbeat returns an executor heartbeat call, useful to detect disconnections.

func Message

func Message(data []byte) *executor.Call

Message returns an executor call with the given parameters.

func SendNoData

func SendNoData(ctx context.Context, sender Sender, r Request) (err error)

SendNoData is a convenience func that executes the given Call using the provided Sender and always drops the response data.

func Subscribe

func Subscribe(unackdTasks []mesos.TaskInfo, unackdUpdates []executor.Call_Update) *executor.Call

Subscribe returns an executor call with the given parameters.

func Update

func Update(status mesos.TaskStatus) *executor.Call

Update returns an executor call with the given parameters.

Types

type Caller

type Caller interface {
	// Call issues a call to Mesos and properly manages call-specific HTTP response headers & data.
	Call(context.Context, *executor.Call) (mesos.Response, error)
}

Caller is the public interface this framework scheduler's should consume

type CallerFunc

type CallerFunc func(context.Context, *executor.Call) (mesos.Response, error)

CallerFunc is the functional adaptation of the Caller interface

func (CallerFunc) Call

func (f CallerFunc) Call(ctx context.Context, c *executor.Call) (mesos.Response, error)

Call implements the Caller interface for CallerFunc

type Request

type Request interface {
	Call() *executor.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() *executor.Call

RequestFunc is the functional adaptation of Request.

func NonStreaming

func NonStreaming(c *executor.Call) RequestFunc

NonStreaming returns a RequestFunc that always generates the same Call.

func (RequestFunc) Call

func (f RequestFunc) Call() *executor.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() *executor.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 *executor.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 ...*executor.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() *executor.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 ...*executor.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 SenderWith

func SenderWith(s Sender, opts ...executor.CallOpt) SenderFunc

SendWith injects the given options for all calls.

func (SenderFunc) Send

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

Send implements the Sender interface for SenderFunc
