Rust Sanitizers Miri

This one walks you through running AddressSanitizer, ThreadSanitizer, and Miri on Rust code to catch memory safety bugs and undefined behavior that the compiler misses. You'll need nightly for most of it, plus the -Zbuild-std flag to instrument the standard library properly. The Miri coverage is especially solid: it explains how to detect dangling pointers, invalid enum discriminants, uninitialized reads, and Stacked Borrows violations with concrete code examples. The sanitizer output interpretation section is genuinely helpful when you're staring at a wall of ASan stack traces. If you write unsafe Rust or maintain FFI bindings, you'll want this in your rotation before merging.
