The README describes it as a way to run Rust code extra carefully by opting into checks that help detect undefined behavior. The tool builds or uses a checked standard library and passes rustc flags that enable stricter runtime behavior, including pointer alignment and null checks, collection consistency checks, strict initialization checks, and extra const-evaluation UB checks. Later versions also document sanitizer support and Apple Main Thread Checker integration on Apple platforms. ### Historique d'adoption cargo-careful is more specialized than general debugging Cargo plugins, but it fills an important space between ordinary `cargo test` and exhaustive interpreters. Crates.io reports more than 169,000 downloads, while the input records Homebrew and Nix packaging. Its author and positioning connect it to Rust's unsafe-code verification culture. The README explicitly compares it with Miri: cargo-careful is less exhaustive but faster, supports arbitrary system and C FFI calls, and works on code Miri may not be able to run. ### Modes d'utilisation Users install it with `cargo install cargo-careful` and run commands such as `cargo +nightly careful test` or `cargo +nightly careful run`. The README says all `cargo test` and `cargo run` flags are supported and that a recent nightly toolchain is required. On first use it may need the `rustc-src` rustup component to perform setup. It also honors common Rust flag sources such as `CARGO_ENCODED_RUSTFLAGS`, `RUSTFLAGS`, and Cargo's `build.rustflags`, and it sets a `cfg(careful)` configuration flag for conditional code. ### Pourquoi les passionnés de paquets s'y intéressent cargo-careful matters to package nerds because it packages unstable compiler and standard-library checking behavior into a repeatable Cargo command. It gives library maintainers a way to add stronger runtime checking to test workflows without rewriting tests for a separate interpreter. It is also a good example of Cargo as a safety-tool host: the package itself is small, but it coordinates rustup components, nightly rustc flags, standard-library rebuilding, sanitizers, and target-specific platform diagnostics. ### Chronologie - 2022-09-22: GitHub repository RalfJung/cargo-careful was created. - 2022-09-22: cargo-careful 0.1.0 was published on crates.io. - 2020s: README documented the relationship with Miri, nightly-only UB checks, sanitizer support, and Main Thread Checker integration. - 2026-04-01: Version 0.4.10 was published. ### Related projects - Miri is the related Rust interpreter/checker that the README recommends for more exhaustive undefined-behavior detection. - rustup and the `rustc-src` component are involved in cargo-careful setup. - Rust nightly compiler flags and sanitizer support are the underlying mechanisms cargo-careful coordinates. ### Sources - GitHub repository API metadata: https://api.github.com/repos/RalfJung/cargo-careful - Official README: https://github.com/RalfJung/cargo-careful#readme - Package-manager adoption from source_facts.package-manager. - crates.io API metadata and versions: https://crates.io/api/v1/crates/cargo-careful ## Notes de sécurité narrow executable package without higher-risk signals. - **Risque Geiger:** vert / faible - narrow executable package without higher-risk signals ## Détails de la base source - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cargo-careful - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Autres enregistrements de gestionnaires de paquets - Nix - cargo-careful: normalized package name match | nixpkgs package indexes: pkgs/by-name/ca/cargo-careful/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Liens liés - [Source-control packages](https://pkg.so/fr/source-control-tools/) - Belongs to a source-control command family. - [Package publisher tools](https://pkg.so/fr/package-publishers/) - Belongs to a package publishing or registry command family. - [Terminal utility packages](https://pkg.so/fr/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/fr/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [rust](https://pkg.so/fr/brew/rust/) - Build dependency declared by Homebrew. - [cargo-instruments](https://pkg.so/fr/brew/cargo-instruments/) - Shares pkgdb curated category or tags: cargo, cli, debugging, developer-tools, rust. - [cargo-binstall](https://pkg.so/fr/brew/cargo-binstall/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-c](https://pkg.so/fr/brew/cargo-c/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-nextest](https://pkg.so/fr/brew/cargo-nextest/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-edit](https://pkg.so/fr/brew/cargo-edit/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-update](https://pkg.so/fr/brew/cargo-update/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-llvm-cov](https://pkg.so/fr/brew/cargo-llvm-cov/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-udeps](https://pkg.so/fr/brew/cargo-udeps/) - Shares pkgdb curated category or tags: cargo, cli, developer-tools, rust. - [cargo-show-asm](https://pkg.so/fr/brew/cargo-show-asm/) - Both packages touch the same language runtime or ecosystem.
