Axum
Axum is an HTTP routing and request-handling library for Rust. RustRover provides dedicated support for Axum, including URL completion, inlay hints for route calls and function handlers, as well as features to browse around and manage endpoints.
Completion
RustRover provides completion for URL paths and query parameters. It works as you type, but you can also call it manually using Ctrl+Space.
URL completion is also available in non-Rust files:
