They're based on timestamp so that they sort *after* any existing ids. * 2. They contain 72-bits of random data after the timestamp so that IDs won't * collide with other clients' IDs. * 3. They sort *lexicographically* (so the timestamp is converted to characters * that will sort properly). * 4. They're monotonically increasing. Even if you generate more than one in * the same timestamp, the latter ones will sort after the former ones. We do * this by using the previous random bits but "incrementing" them by 1 (only * in the case of a timestamp collision). */ export declare const nextPushId: (now: number) => string; export declare const successor: (key: string) => string; export declare const predecessor: (key: string) => string;
