SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Helps developers and code-generating agents avoid runtime panics and behavioral regressions caused by Axum changes introduced in 0.8.x by providing concise, verified migration guidance and API notes to apply before writing or refactoring Axum code.

Core Features & Use Cases

Migration Guidance: Clear mapping of breaking changes such as new path parameter syntax, native async extractor traits, OptionalFromRequestParts semantics, and updated WebSocket message types.
API Highlights: Summarizes new convenience types and router APIs like NoContent, method_not_allowed_fallback, reset_fallback, WebSocketUpgrade::selected_protocol, and ResponseAxumBodyLayer.
Use Case: When upgrading a Rust service or generating handlers with an AI assistant, consult this patch to rewrite routes, extractor implementations, and WebSocket handling to match Axum 0.8+ requirements and avoid runtime panics.

Quick Start

Use the axum-knowledge-patch to scan and update your repository for Axum 0.8 path syntax, extractor changes, and WebSocket message types.

FAQPage Schema

How do I migrate Rust web services to Axum 0.8 without runtime panics?▼

Migrate Axum 0.8 code by updating path parameter syntax, applying native async extractor traits, and enforcing Sync handler bounds to prevent runtime panics. Curated knowledge patches map these breaking changes to ensure refactored routes and handlers match the new API requirements.

What breaking changes were introduced for Axum extractors in 0.8?▼

Axum 0.8 extractor changes include native async extractor traits and modified OptionalFromRequestParts semantics. Developers must update custom extractor implementations to align with these trait changes and avoid behavioral regressions during request processing.

Why do my Axum WebSocket handlers fail after upgrading to 0.8?▼

Axum WebSocket handlers fail due to updated message types requiring Utf8Bytes and Bytes. You must rewrite WebSocket handling logic to match these new message type requirements and prevent runtime type mismatches during message processing.

How do I update routing syntax for Axum 0.8?▼

Update Axum 0.8 routing syntax by applying the new path parameter conventions and using updated router APIs. Enforcing the new path syntax prevents routing behavioral regressions and ensures path extraction works correctly in refactored handlers.

Can I use the new NoContent and method_not_allowed_fallback APIs in Axum 0.8?▼

Axum 0.8 introduces convenience types like NoContent and router fallbacks including method_not_allowed_fallback and reset_fallback. You can implement these new router APIs to handle empty responses and method routing edge cases cleanly.

What are the limitations of relying on manual Axum 0.8 migration?▼

Manual Axum 0.8 migration risks missing subtle breaking changes like WebSocket message type updates and Sync handler bounds. Without verified migration guidance, refactored Rust services may introduce hidden behavioral regressions and runtime panics.
