Krabby is an experimental Rust compiler project that aims to achieve significantly faster compilation times by rethinking compiler architecture from the ground up. Unlike the main Rust compiler (rustc), which faces challenges in making large-scale architectural changes due to stability requirements, Krabby prioritizes performance and exploration of novel optimization approaches. The project represents an ambitious attempt to push the boundaries of Rust compilation speed, though its success remains uncertain given the complexity of the task.
Background
Rust is a systems programming language known for its safety guarantees, but its compilation times have been a common point of criticism among developers. The official Rust compiler (rustc) has seen incremental improvements, but faces challenges in making major architectural changes due to its large codebase and stability requirements.
