In the previous section, we saw how the compiler stops us from sharing the data. If a child thread accesses data mutably, it is moved because Rust won't allow it to be used in the parent thread as the child thread might deallocate it, leading to a dangling pointer dereference in the main thread. Let's explore the idea of thread-safety and how Rust's type systems achieves that.
thread-safety in Rust
What is thread-safety?
thread-safety is the property of a type or a piece of code that, when executed or accessed by multiple threads, does not lead to unexpected behavior. It refers to the idea that data is consistent for reads while being safe from corruption when multiple threads write to it.
Rust only protects...
