func (*Instance) Dispatch added in v0.10.0 

func (inst *Instance) Dispatch(ctx context.Context, method string, param interface{}) (res interface{}, cur Cursor, err error)

Dispatch is a system for handling calls to lib. Should only be called by top-level lib methods.

When programs are using qri as a library (such as the `cmd` package), calls to `lib` will arrive at dispatch, before being routed to the actual implementation routine. This solves a few problems:

  1. Multiple methods can be running on qri at once, dispatch will schedule as needed (TODO)
  2. Access to core qri data structures (like logbook) can be handled safetly (TODO)
  3. User identity, permissions, etc is scoped to a single call, not the global process (TODO)
  4. The qri http api maps directly onto dispatch's behavior, leading to a simpler api
  5. A `qri connect` process can be transparently forwarded a method call with little work

At construction time, the Instance registers all methods that dispatch can access, as well as the input and output parameters for those methods, and associates a string name for each method. Dispatch works by looking up that method name, constructing the necessary input, then invoking the actual implementation. Dispatch returns the custom value from the implementation, then a non-nil Cursor if the method supports pagination, then an error or nil.
