dmutex 1.0.1

Asynchronous locks and reentrant locks for Dart, enabling smooth concurrency control in your applications.

dmutex

dmutex is a Dart package that provides a smart locking mechanism to control concurrency in your Dart applications. It helps prevent chaotic execution and ensures orderly processing of tasks in a single-threaded environment.

Overview

In a single-threaded programming world like Dart, managing concurrent execution can still be challenging, especially when dealing with asynchronous tasks. dmutex comes to the rescue by providing a specialized locking mechanism known as a "mutex" (short for "mutual exclusion"). Just like a special key ensures only one person (or "task") is allowed to access a particular resource at a time, dmutex helps ensure that only one task can access a critical section at a time.

dmutex helps you maintain order and prevent conflicts when working with asynchronous tasks, even in a single-threaded environment like Dart.

Features

• Provides a smart locking mechanism for controlling concurrency.
• Prevents multiple asynchronous tasks from accessing critical sections simultaneously.
• Offers both basic locking (DLock) and reentrant locking (ReentrantDLock).
• Helps maintain execution order and synchronization.
• Easily integrates with your Dart applications.

Installation

Add this to your pubspec.yaml:

dependencies:
  dmutex: ^1.0.0

Then, run dart pub get to install the package.

Usage

Here's how you can use the classes provided by this package.

DLock

An asynchronous lock implementation that provides exclusive access control.

import 'package:dmutex/dmutex.dart';

void main() async {
  final dLock = DLock();

  await dLock.withLock(() async {
    // Critical section
  });
}

ReentrantDLock

A reentrant lock that allows nested synchronized blocks.

import 'package:dmutex/dmutex.dart';

void main() async {
  final reentrantDLock = ReentrantDLock();

  await reentrantDLock.withLock(() async {
    // Outer synchronized block

    await reentrantDLock.withLock(() async {
      // Inner synchronized block
    });
  });
}
