Thanks. I actually don't know much about concurrency/lock so I just took whatever the post said. I shall quote: Galen Hunt Author Distinguished Engine

Thanks. I actually don't know much about concurrency/lock so I just took whatever the post said. I shall quote: Galen Hunt Author Distinguished Engineer at Microsoft 3d @Sukesh Ashok Kumar No memory safety. No concurrency safety. Of course, for a single C or C++ code base, these qualities can be achieved with extraordinary discipline and effort--and lost with just a single mistake. With Rust, can be proven by the compiler.

I see, most likely thread-safety then. Rust will prevent accessing data shared between threads unless you first lock a mutex, use an atomic, etc. Or rather, it gives abstractions so that higher-level types in stdlib and other libraries can prevent such access. The low-level implementation of the Mutex/etc types themselves do the same thing C and C++ do, via unsafe blocks, atomic primitives, fences, etc.
