Blazingly Fast or Blazingly Hyped? A Reality Check on Rewriting in Rust
Summary
JetBrains' Rust blog offers a reality check on rewriting software in Rust, discussing RIIR (Rewrite It In Rust) across drop-in replacements, alternatives, and self-rewrites. It covers benefits (memory safety, performance), risks (new bugs, longer timelines), notable case studies (Prisma, Loglog Games, curl/hyper), licensing considerations, and best practices for incremental rewrites with emphasis on testing and governance.
