A Go library for safe asynchronous function execution with panic recovery and error stack traces.
Async is a Go library designed to safely execute functions asynchronously with built-in panic recovery and error stack traces. It solves the problem of debugging failures in concurrent Go programs by providing detailed error information and simplifying the management of multiple goroutines.
Go developers building applications that require concurrent execution of tasks, especially those needing robust error handling and panic recovery in asynchronous operations.
Developers choose Async because it provides a safer alternative to manual goroutine management, automatically handles panics, and offers detailed error stacks that make debugging concurrent failures significantly easier.
A safe way to execute functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery.

Automatically recovers panics in goroutines and converts them to errors, as highlighted in the README's key features, preventing application crashes from async failures.
Provides error stacks to identify root causes, simplifying debugging of concurrent failures, which is a core value proposition mentioned in the description.
Offers an API to manage tasks without directly using WaitGroup, as shown in the usage example, reducing boilerplate code for async execution.
Allows limiting concurrent goroutines with methods like WithLimit, demonstrated in the README, to control resource usage effectively.
Supports Go's context for cancellation and timeout handling, ensuring better control over async operations, as indicated in the key features.
Requires all async functions to have the signature func(ctx context.Context) error, which may not accommodate use cases needing different return types or parameters.
The additional layers for panic recovery and error stacking introduce overhead compared to native goroutines, potentially impacting high-throughput scenarios.
Lacks advanced features like result aggregation or complex error handling patterns found in more mature libraries, limiting its utility for intricate concurrency needs.
