Bun's experimental Rust rewrite hits 99.8% test compatibility on Linux x64 glibc

Bun, the high-performance JavaScript runtime, has reached a major milestone in its experimental Rust rewrite. According to recent updates, the Rust-based implementation has achieved a 99.8% pass rate in its test suite on Linux x64 glibc environments. Originally authored primarily in Zig, the move towards Rust aims to leverage the language's robust ecosystem and memory safety features without compromising on Bun's signature speed. This high level of compatibility suggests that the experimental version is nearing feature parity with the stable release, marking a significant step forward in the project's long-term architecture and stability.
