rust-lang/rust has 2,746,357 source lines of code out of 3,216,511 total lines across 8,493 files, counted with tokei from the main ref at commit 96a18bf5ffa2 on October 29, 2026. Tests, docs and generated files are excluded under OctoCounts' canonical public options.

OctoCounts produced this report by resolving rust-lang/rust to commit 96a18bf5ffa2, downloading the repository source archive, and counting files selected by the effective rules 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; an exact reproduction needs the same commit, engine version, and effective counting rules.

## Counting rules and retention

rust-lang/rust: tokei-14.0.0, policy directories-v1; docs excluded, tests excluded, generated excluded. Excluded directory names: .cache, .generated, .git, .next, __tests__, build, dist, doc, docs, documentation, fixtures, gen, generated, node_modules, target, test, tests, vendor. Ignored languages: none. Repository declarations: off. Exclusions are rule-based; they do not prove that every test, document or generated file was removed.

Saved reports remain subject to cache cleanup and replacement. Export the JSON or text for durable citation; live repository URLs can change.

## Repository size insights

This is a very large codebase by counted code lines. Code represents 85.4% of all lines, comments represent 6.9%, and the repository averages 323 code lines per file. Rust accounts for 76.5% of counted code.
