   The State of Rust Ecosystem 2025

   JetBrains' 2025 Developer Ecosystem Survey reveals Rust's continued growth with 30% of users being newcomers and 26% using it professionally. The language attracts experienced developers from Python, Java, and C++ backgrounds, primarily for systems programming, CLI tools, and backend development. Most Rust projects target Linux production environments and integrate with JavaScript/TypeScript and Python. AI coding assistants have seen widespread adoption, with 78% of Rust developers actively using tools like ChatGPT and GitHub Copilot. The ecosystem shows maturity through improved tooling, educational resources, and expanding use cases across embedded systems, WebAssembly, and infrastructure.

   JetBrains introduces Java to Kotlin converter for Visual Studio Code

   JetBrains has released a Java to Kotlin converter extension for Visual Studio Code, available on the VS Code Marketplace. The extension lets developers convert individual Java files to Kotlin via a context menu action, using the same conversion engine found in JetBrains IDEs combined with LLMs to produce idiomatic Kotlin output. It supports multiple LLM backends including GitHub Copilot, Ollama, and OpenRouter, and is designed to reduce manual effort when migrating legacy Java codebases or transitioning projects to Kotlin.

   Write Modern Go Code With Junie and Claude Code

   JetBrains has released a plugin called go-modern-guidelines that helps AI coding agents like Junie and Claude Code generate modern, idiomatic Go code. The problem it solves: AI models tend to produce outdated Go patterns due to training data cutoffs and frequency bias toward older code. The plugin reads the Go version from go.mod and instructs agents to use features available up to that version—for example, using slices.Contains() instead of manual loops, or errors.AsType[T]() instead of the older errors.As() pattern. In Junie 2xx.620.xx+, it works out of the box. For Claude Code, it requires installing via a few slash commands in a session.
