Contract
- attribute.Key provides typed constructors like Int and String that return KeyValue pairs, where Int maps Go int to INT64 Value type and empty keys produce invalid KeyValue pairs.
- key.Defined() returns true for non-empty keys and false for empty keys
- key.Int(200) constructs a KeyValue with Value.Type() equal to attribute.INT64 and AsInt64() equal to 200
- key.String("GET") constructs a KeyValue with Value.Type() equal to attribute.STRING and AsString() equal to "GET"
- emptyKey.String("value").Valid() evaluates to false because emptyKey is not defined
- key.IntSlice([]int{100, 200, 300}) constructs a KeyValue with INT64SLICE Value type
- attribute.NewSet with KeyValue pairs allows key lookup via set.HasValue(key) and set.Value(key)
