Rust IDEs (e.g., rust-analyzer and RustRover) must reimplement the compiler frontend—not reuse rustc—to achieve low-latency interactivity; their core challenge lies in handling incomplete code, incremental parsing, and on-demand semantic analysis.
入选理由：Rust IDE 需重写编译器前端（约50%功能），因 rustc 优化吞吐而 IDE 优化延迟，典型场景：用户输入 '.' 后需毫秒级补全响应。
