#rust Miri is a tool that detects bugs in unsafe Rust code by finding undefined behavior—situations where your program violates safety rules and can behave unpredictably. When you write unsafe code, you bypass Rust's normal safety checks, so you must manually ensure your code follows strict requirements like proper memory alignment, no data races, and correct pointer usage. Miri catches violations of these requirements by running your code in a special interpreter that monitors every operation. It detects problems like out-of-bounds memory access, use-after-free errors, uninitialized data, and misaligned pointers. You can easily use Miri by installing it with Rust's nightly toolchain and running `cargo miri test` on your project. The benefit is that Miri finds subtle bugs that would otherwise cause crashes or security vulnerabilities in production, making it an essential tool for anyone writing unsafe Rust code. https://github.com/rust-lang/miri
