Systems & Languages
mrustc Rust Compiler
mrustc is an alternative Rust compiler written in C++ that can build a working copy of rustc but is not intended for daily use. Its primary goal is bootstrapping the official Rust compiler, treating invalid input as a bug in mrustc rather than the source program.
