@apiratorjs/locking/dist/src/semaphore.d.ts

A lightweight library providing both local and distributed locking primitives (mutexes, semaphores, and read-write locks) for managing concurrency in Node.js.

import { AcquireParams, IReleaser, ISemaphore, SemaphoreToken } from "./types";
export declare class Semaphore implements ISemaphore {
    readonly maxCount: number;
    private _freeCount;
    private _queue;
    private _waitingForAnyUnlockListeners;
    private _waitingForFullyUnlockListeners;
    constructor(maxCount: number);
    waitForFullyUnlock(): Promise<void>;
    waitForAnyUnlock(): Promise<void>;
    runExclusive<T>(fn: () => Promise<T> | T): Promise<T>;
    runExclusive<T>(params: AcquireParams, fn: () => Promise<T> | T): Promise<T>;
    freeCount(): Promise<number>;
    acquire(params?: {
        timeoutMs?: number;
    }, acquireToken?: string): Promise<IReleaser<SemaphoreToken>>;
    cancelAll(errMessage?: string): Promise<void>;
    isLocked(): Promise<boolean>;
    private release;
