Types

type Function

}

func (*Function) Invoke

func (f *Function) Invoke(ctx context.Context, data []byte) ([]byte, error)

Invoke invoke a function. TODO: this is likely be highly inefficient as the model is TODO: loaded for each invocation but at this stage I don't TODO: have enough knowledge of memory management to make TODO: things better.
