ReactiveFlags extension type
Bit flags describing the state of a ReactiveNode.
All state a node needs during propagation lives in a single int,
checked and mutated with bitwise operations — one field read instead of
several boolean fields. The extension type wrapper gives the flags a
distinct static type at zero runtime cost.
Flags de bits descrevendo o estado de um ReactiveNode.
Todo o estado que um nó precisa durante a propagação vive em um único
int, checado e mutado com operações bitwise — uma leitura de campo em
vez de vários booleans. O extension type dá às flags um tipo estático
distinto com custo zero em runtime.
