About:
cargo-careful is a Cargo subcommand that executes Rust programs under a custom Miri-based interpreter. It provides additional checks beyond standard compilation, such as detecting undefined behavior and memory safety issues. This tool helps developers validate the correctness of their unsafe Rust code more rigorously.
Key Features:
  • Detects undefined behavior in unsafe code blocks
  • Uses a Miri-based interpreter for deep analysis
  • Integrates seamlessly as a Cargo subcommand
  • Provides detailed diagnostics for found issues
Use Cases:
  • Auditing unsafe Rust code for memory safety bugs
  • Validating correctness in low-level system libraries
  • Continuous integration checks for critical Rust projects
Alternatives:
  • Miri – Miri is the underlying engine; cargo-careful provides a convenient wrapper for running programs with it.
  • Valgrind – Valgrind is a general-purpose memory debugger; cargo-careful is Rust-specific and catches undefined behavior at the abstract machine level.
