Types

type Client

type Client interface {
	// Factory functions of actual (not abstract) users and courses.
	MakeUser(userID string, password string) (icarus.User, error)
	MakeCourse(name string, desc string, token string) (icarus.Course, error)
}

Client is in icarus (server part).

Server part invokes dispatcher to send task,

(most times the only needed work is
 to use standard dispatcher functions)

and the satellite part do the actual work.

func GetHandle

func GetHandle(handle string) (Client, error)

type Worker

type Worker interface {
	Login(data []string) []string
	ListCourse(data []string) []string
	Elect(data []string) []string
}

Worker is in icarus-satellite.

What worker needs to do is to handle server's subtask and do actual response. All datum are transfered in []string so the worker need to understand server's

request correctly and generate suitable response. Errors should be coded in
response so worker cannot generate any Go-style errors.

func GetWorker

func GetWorker(handle string) (Worker, error)
