history

Project history and usage

cargo-llvm-lines measures the number and size of LLVM IR instantiations for generic functions in a Rust program. Its README frames the output as a way to find code with the highest leverage for improving compilation metrics.

Project history

The crate first appeared on crates.io in November 2017 as version 0.1.0. The README credits the idea to eddyb's suggestion for counting monomorphized functions while debugging compiler memory use, executable size, and compile time.

Adoption history

The package is available through Homebrew and Nix according to the input facts, and crates.io reported 134,082 downloads when checked on 2026-06-30. Its audience is narrower than test runners or build tools, but it is well known among Rust developers investigating monomorphization bloat.

How it is used

Users run cargo llvm-lines to see total LLVM IR lines, number of copies, and function names, optionally using -p to inspect a package in a multi-crate project or release/LTO settings for a broader view.

Why package nerds care

It is a package-nerd tool because it exposes otherwise hidden codegen costs in dependency and generic-heavy Rust crates, helping maintainers decide where small API or generic changes can reduce compile time and binary size.

Timeline

2017: First crates.io release 0.1.0.
2026: Crates.io latest version 0.4.46 and Homebrew stable version 0.4.46.
