rust-lang/rust has 2,729,711 source lines of code out of 3,193,917 total lines across 8,431 files, counted from the main ref at commit 6bb1652a020e by the OctoCounts tokei engine on 2026-09-22. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving rust-lang/rust to commit 6bb1652a020e, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
