# Library-ification and analyzing Rust · baby steps

**[Niko Matsakis - baby steps](https://daily.dev/sources/babysteps)** · 12 min read · 0 upvotes · 0 comments

## Summary

A vision for refactoring the Rust compiler (rustc) into a set of independent, well-defined libraries with clean APIs — a concept called 'library-ification'. Combined with on-demand (query-based) analysis, this architecture would allow sharing components between rustc and rust-analyzer, make the compiler more accessible to contributors, and enable third-party analysis tools like Prusti or Clippy to directly leverage compiler internals (borrow checker results, MIR, type information) without resorting to hacks. The post also discusses stability and semver considerations for such public compiler APIs.
