async-std vs Smol

Developers should learn async-std when building high-performance, concurrent applications in Rust, such as web servers, networking tools, or data processing pipelines that require efficient I/O handling meets developers should learn smol when working on projects that require minimal resource usage, such as in embedded devices or educational settings where clarity and ease of learning are priorities. Here's our take.

async-std

Nice Pick

Developers should learn async-std when building high-performance, concurrent applications in Rust, such as web servers, networking tools, or data processing pipelines that require efficient I/O handling

Pros

• It's particularly useful for projects that need to manage many simultaneous connections without blocking threads, offering a simpler API compared to lower-level async primitives
• Related to: rust, tokio

Cons

• Specific tradeoffs depend on your use case

Smol

Developers should learn Smol when working on projects that require minimal resource usage, such as in embedded devices or educational settings where clarity and ease of learning are priorities

Pros

• It is particularly useful for teaching programming basics to novices, as its stripped-down syntax reduces cognitive load and allows focus on algorithmic thinking rather than language intricacies
• Related to: c, python

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. async-std is a library while Smol is a language. We picked async-std based on overall popularity, but your choice depends on what you're building.

The Bottom Line

async-std wins

Based on overall popularity. async-std is more widely used, but Smol excels in its own space.
