Chapter 2, Technical error | Mutex

[siddharthteli12]

Type of error

Minor technical mistake

Location of the error

All the other concurrency primitives, such as mutexes and condition variables, are implemented using atomic operations.

Description of the error

Aren't Mutex implemented using OS-level synchronization primitives, which may involve atomic operations? The above statements suggest that Mutex in Rust directly uses atomics within its implementation.
