Creating Async-Runtime-Generic Libraries in Rust: Strategies and Examples

Learn about creating async-runtime-generic libraries in async Rust applications, exploring three key strategies along with practical examples found in the Rust ecosystem.

Published 1 year ago by https://github.com/tyt2y3 on www.sea-ql.org

Abstract

The article delves into the importance of creating async-runtime-generic libraries in Rust for better encapsulation, faster compilation, portability, and correctness testing against different async runtimes. It presents three strategies with examples: defining your own AsyncRuntime trait, abstracting async runtimes internally with feature flags, and maintaining an async runtime abstraction crate.

Discussion

How this relates to indie hacking and solopreneurship.

Relevance

This article is crucial for you as an indie hacker working on async Rust applications, highlighting the benefits of creating async-runtime-generic libraries to enhance code quality, performance, portability, and correctness testing. It offers practical strategies and examples to implement this effectively in your projects.

Applicability

To apply the insights from this article, if already using Rust for async applications, consider implementing async-runtime-generic libraries to improve code organization, compilation speed, and testing flexibility against different async runtimes. Explore the three strategies shared in the article and adapt them to suit your specific project requirements.

Risks

One potential risk to consider when creating async-runtime-generic libraries is the complexity introduced by managing multiple async runtimes and ensuring compatibility across different implementations. Additionally, relying on feature flags for abstracting async runtimes could lead to increased code complexity and maintenance overhead.

Conclusion

Looking ahead, the trend of developing async-runtime-generic libraries in Rust is likely to grow as developers seek enhanced code modularity, performance optimization, and broader compatibility with different async runtimes. Embracing these practices can future-proof your projects and streamline the adoption of new async runtimes.
