SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It prevents Axum handler return-value mistakes that either fail compilation or silently produce incorrect HTTP responses, especially around IntoResponse / IntoResponseParts tuple rules, status/header/body ordering, redirect status codes, cookie jar behavior, and the Axum 0.8 body type.

Core Features & Use Cases

  • IntoResponse return typing: Ensures your handler returns a type that actually implements IntoResponse (e.g., Json, Html, Redirect, StatusCode, Response), avoiding Handler trait bound failures.
  • Tuple composition correctness: Guarantees correct use of (StatusCode, parts..., body) and enforces that the body is the final tuple element while earlier elements are IntoResponseParts.
  • Status, headers, and cookies right: Correctly combines status and headers (including AppendHeaders for multiple Set-Cookie), picks correct Redirect constructors (303/307/308 only), and ensures the modified CookieJar is returned.
  • Axum 0.8 body requirement: Uses axum::body::Body instead of hyper::Body when manually building a Response.
  • Common scenarios: Returning JSON/HTML/raw bytes, setting response headers, redirecting after POST/PUT, mapping fallible results to responses with Result, and applying cookie-based session/auth patterns.

Quick Start

Use axum-syntax-responses when your Axum handler must return a proper status/headers/body (or cookies/redirects) or when compilation fails with an IntoResponse/Handler trait-bound error.

Frequently Asked Questions about axum-syntax-responses

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix an Axum handler failing to compile with an IntoResponse trait bound error?▼

Axum handler IntoResponse trait bound errors occur when return types lack valid implementations, incorrect tuple ordering, or wrong body types. Ensure the body is the final tuple element, earlier elements implement IntoResponseParts, and use axum 0.8 body typing for manually built responses.

What is the correct tuple ordering for Axum responses with status, headers, and a body?▼

Correct Axum response tuple ordering places StatusCode, headers, and other parts first, with the body as the final element. Earlier elements must implement IntoResponseParts, while the last element provides the response body like Json or Html.

How do I return a Redirect response in Axum after a POST or PUT request?▼

Returning a Redirect response in Axum after POST or PUT requires selecting the correct Redirect constructor. Use 303 See Other for post-redirect-get patterns, 307 for temporary redirects preserving the method, and 308 for permanent redirects to ensure correct HTTP semantics.

Can I use hyper::Body when manually building an Axum 0.8 Response?▼

Axum 0.8 manual Response construction cannot use hyper::Body and requires axum::body::Body instead. Using hyper::Body causes compilation failures due to Axum 0.8 body typing changes, so always use axum::body::Body for manually built responses.

How do I set multiple cookies on an Axum response using a CookieJar?▼

Setting multiple cookies on an Axum response using a CookieJar requires modifying the jar and returning it from the handler. Use axum-extra CookieJar variants and ensure the modified CookieJar is returned safely to apply Set-Cookie headers correctly.

Why does my Axum handler return a 200 OK status when I specified a different StatusCode in a tuple?▼

Axum handler tuple responses use the specified StatusCode, but silent incorrect HTTP responses happen when tuple composition is wrong. Ensure StatusCode is placed before the body, implements IntoResponseParts correctly, and the body remains the final tuple element.
