Surelock: Deadlock-Free Mutexes for Rust
Summary
An in-depth overview of Surelock, a Rust crate designed to prevent deadlocks in multi-mutex code. It explains Coffman conditions, introduces two complementary mechanisms (LockSet and Level<N>), and demonstrates compile-time and runtime safety guarantees, no_std compatibility, and an escape hatch for advanced cases. The piece also compares Surelock to prior art like happylock and lock_tree, and discusses trade-offs and practical usage for embedded or no_std targets.
