A simple implementation of a read-write lock with shared read

export declare class ReadWriteLock {
    state: Int32Array;
    static readonly READERS = 0;
    static readonly WRITER = 1;
    static readonly WAITERS = 2;
    timeout: number;
    constructor(sharedBuffer: SharedArrayBuffer, config?: {
        timeout?: number;
    });
    /** Acquire a read lock (async). Blocks if a writer is active or waiting. */
    readLock(): Promise<void>;
    /** Release a read lock. Wakes a waiting writer if this was the last reader. */
    readUnlock(): void;
    /** Acquire a write lock (async). Blocks until no readers or writers are active. */
    writeLock(): Promise<void>;
    /** Release the write lock. Wakes the next waiter(s) based on priority. */
    writeUnlock(): void;
