What it is

cargo-bloat is a Rust CLI tool that analyzes compiled binaries (ELF, Mach-O, PE) to identify which functions and crates consume the most disk space in the .text section. It provides granular per-function or per-crate size breakdowns via a formatted table, helping developers optimize binary bloat without instrumentation overhead. Monolithic CLI binary: src/main.rs is the entry point, src/process_crate handles core analysis logic, src/crate_name.rs resolves symbol metadata, and src/table.rs formats tabular output. All logic is single-crate with no module subdivision; dependencies handle binary parsing (pdb for PDB, binfarce for generic binary manipulation, json for processing intermediate…

Start here

Open these first:

• src/main.rs — Entry point that orchestrates CLI argument parsing, binary format detection, and analysis invocation—every contributor must…
• src/crate_name.rs — Core symbol extraction and demangling logic that parses binary metadata and maps symbols to crates—essential for the…
• src/table.rs — Output formatting and display logic that renders results in human-readable tables—critical for UX and result presentation.
• Cargo.toml — Defines all external dependencies (memmap2, pdb, binfarce, regex) that enable multi-format binary analysis—architectural…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/RazrFalcon/cargo-bloat.git
cd cargo-bloat
cargo build --release
./target/release/cargo-bloat --help
# Or install directly:
cargo install cargo-bloat

Daily commands:

After cargo install cargo-bloat, run it as a cargo subcommand on any Rust project: cargo bloat --release (analyzes target/release binary), cargo bloat --release --crates (groups by crate), `cargo bloat --release -…

Key cautions & unknowns

• Stale — last commit 2y ago
• Single-maintainer risk — top contributor 80% of recent commits
• No environment variables required. Binary format parsing relies on binfarce and pdb crates, which may fail silently on malformed binaries (returns '[Unknown]' crate as fallback). The regex-filter feature must be…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
