Simple map-like interface for encoded storage w/ bigint keys

protomap.ts

declare class ProtoMessage {
  serializeBinary(): Uint8Array;
  static deserializeBinary(bytes: Uint8Array): any;
}

export default class ProtoMap<K, V extends ProtoMessage> {
  private map: Map<K, ReturnType<ProtoMessage["serializeBinary"]>> = new Map;

  constructor(private message: typeof ProtoMessage) {}

  set(id: K, data: V) {
    return this.map.set(id, data.serializeBinary());
  }

  get(id: K): V | undefined {
    const data = this.map.get(id);

    if (data) return this.message.deserializeBinary(data);
  }

  has(id: K) {
    return this.map.has(id);
  }

  delete(id: K) {
    return this.map.delete(id);
  }
}
