SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides guidance for building production-grade REST APIs in Rust with type-safe input validation, OpenAPI documentation via utoipa, and interactive Swagger UI.

Core Features & Use Cases

  • Edge input validation using validator and derive macros.
  • Code-first OpenAPI with utoipa for automatic docs.
  • Swagger UI exploration to inspect endpoints locally.

Quick Start

Use this skill to scaffold an Axum API with validated requests and /api-docs openapi.json accessible at /swagger-ui.

FAQPage Schema
How do I build a REST API in Rust with automatic OpenAPI documentation?

Use Axum with utoipa to build REST APIs that generate OpenAPI specs automatically. utoipa derives OpenAPI schemas from your Rust types, eliminating manual documentation and keeping specs synchronized with code.

How can I validate request inputs in a Rust API before processing?

Apply validator and derive macros to your request structs for edge input validation. The validator crate enforces constraints at the type level, rejecting invalid requests with 400 responses before business logic runs.

Can I explore my Rust API endpoints interactively during development?

Yes, Swagger UI integrates with utoipa to expose an interactive /swagger-ui endpoint. Visit it locally to inspect all endpoints, schemas, and response types without leaving your browser.

What's the best way to enforce type-safe API contracts in Rust?

Use code-first patterns with Validate and ToSchema derives on request types. This enforces contracts at compile time, auto-generates OpenAPI documentation, and guarantees validation logic runs on every request.

Do I need Swagger UI to expose my Rust API's OpenAPI specification?

No. utoipa generates /api-docs/openapi.json accessible to any OpenAPI client. Swagger UI is optional—use it for interactive exploration or consume the JSON spec with other tools.
