ToMapWithValueSelector Operator

Overview

Transform the Observable items into a Single emitting a map. It accepts:

• A function that transforms each item into its corresponding key in the map.
• A function that transforms each item into its corresponding value in the map.

Example

observable := rxgo.Just(1, 2, 3)().
	ToMapWithValueSelector(func(_ context.Context, i interface{}) (interface{}, error) {
		return i.(int) * 10, nil
	}, func(_ context.Context, i interface{}) (interface{}, error) {
		return i, nil
	})

Output:

map[10:1 20:2 30:3]
