Modernize Rust Async Patterns

Rust async APIs can be hard to design when traits, closures, and dispatch choices interact. This skill gives practical guidance for modern native async patterns and async-trait migration.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "async-patterns-guide" from https://skillstore.io/skills/emillindfors-async-patterns-guide.md and its manifest at https://skillstore.io/api/skills/emillindfors-async-patterns-guide/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "async-patterns-guide". A developer asks whether async-trait is needed for a repository trait used only with generics.

Expected outcome:

The skill recommends native async functions in traits, explains the Rust 1.75 requirement, and notes the performance benefit of static dispatch.

Using "async-patterns-guide". A maintainer wants to support a list of async plugins through trait objects.

Expected outcome:

The skill explains why async-trait may still be appropriate, because dynamic dispatch requires object-safe trait behavior.

Using "async-patterns-guide". A team wants to modernize callback-heavy async processing code.

Expected outcome:

The skill suggests modern async closure patterns and asks the team to verify the project Rust version before migration.

What You Can Build

Review Async Trait Design

Check whether a Rust trait can use native async functions without async-trait.

Plan Dependency Migration

Assess where async-trait can be removed while preserving behavior and compatibility.

Compare Dispatch Strategies

Decide between generic static dispatch and dynamic trait objects for async APIs.

Try These Prompts

Check Trait Choice 
Review this Rust async trait design. Tell me if native async functions in traits are enough, or if async-trait is needed.
Plan Async-Trait Migration 
Find places where this crate can move from async-trait to native async traits. Explain the required Rust version and compatibility risks.
Compare Dispatch Options 
Compare static dispatch and dynamic dispatch for this async Rust API. Recommend the design with the clearest tradeoffs.
Design Plugin Async APIs 
Design an async plugin interface for this Rust project. Explain when dyn Trait support justifies async-trait and where native traits fit.

Best Practices

  • Confirm the project MSRV before recommending native async trait features.
  • Use native async traits when static dispatch satisfies the API requirements.
  • Keep async-trait when object safety and dyn Trait usage are required.

Avoid

  • Removing async-trait from APIs that still require trait objects.
  • Ignoring MSRV constraints when suggesting Rust 1.75 or 1.85 features.
  • Treating static dispatch and dynamic dispatch as interchangeable.

Frequently Asked Questions

Does this skill execute code?
No. It provides guidance using Read and Grep access only.
When should I use native async functions in traits?
Use them when Rust 1.75 or later is available and static dispatch is acceptable.
When is async-trait still useful?
It is useful when you need dyn Trait support, object safety, or older Rust compatibility.
Does it cover async closures?
Yes. It covers modern async closure patterns for Rust 1.85 and later.
Can it verify performance improvements?
No. It explains expected tradeoffs, but users must run their own benchmarks.
Is it specific to one async runtime?
No. The guidance focuses on language patterns, traits, closures, and dispatch choices.
