RustRover 2026.2 ships several notable improvements: axum and reqwest support with URL resolution, endpoint discovery, and route-handler navigation; Ferrocene toolchain integration via criticalup; an interactive declarative macro tester showing expansion and input-output mapping; Criterion benchmark run configurations launchable from the gutter; smarter import cleanup with fewer false positives; local variable completion inside struct literals; .env file support with completion and navigation; a faster Copy Reference action for fully qualified Rust paths; and smoother editing in split/remote mode. On the AI side, the release adds an agent skills manager for persistent domain knowledge, support for third-party OpenAI-compatible providers in AI completion, and native GitHub Copilot integration via a JetBrains-Microsoft partnership.
