# What's New in RustRover 2026.2 Axum support, Ferrocene integration and productivity boosts - **Source:** [The JetBrains Blog](https://brifing.si/source/782eebd1-7be8-49cc-b27c-e552516691b2) - **Published:** 2026-07-22 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/5e4ffd7b-b7aa-409c-944f-c9980bd0fb8e ## Enhanced navigation for axum and reqwest RustRover 2026.2 introduces endpoint discovery and route-handler navigation for axum-based projects. URL resolution and client call generation are now easier with route references and inlay hints that make endpoint relationships visible at a glance. ## Ferrocene toolchain support Ferrocene users can now benefit from RustRover's code completion, analysis and inspection features. The IDE supports criticalup-managed Ferrocene toolchains and provides setup guidance to simplify configuration. ## Revolution in macro development The new interactive declarative macro tester lets you see how your macro inputs expand directly in the IDE. Understanding and fixing matching errors during macro development becomes significantly easier with real-time input-output visualization. ## Productivity enhancements Run Criterion benchmarks from the IDE, enjoy smarter import cleanup, and leverage local variable completion in struct literals. With .env file support, your development workflow becomes more streamlined and efficient. ## Improved split mode experience Remote developers get a smoother editing experience in split mode with optimized performance for typing and code changes. The improvements bring the feel closer to working in a standard local IDE environment. ## AI-powered development Agent skills manager enables AI assistants to automatically learn project context. Integrate third-party AI providers and use GitHub Copilot support. Code completion suggestions are now smarter and more context-aware than ever. ## Sources covering this story - https://blog.jetbrains.com/rust/2026/07/22/whats-new-in-rustrover-2026-2/ — --- _Summary written by Brifing from the original reporting.
