Rust is safe from race conditions, because race conditions are memory errors.

You should read [1] to understand how Rust achieves this.

Quoting some more relevant stuff from the nomicon. The linked article is short and sweet.

A data race has Undefined Behavior, and is therefore impossible to perform in Safe Rust.


However Rust does not prevent general race conditions.

This is pretty fundamentally impossible, and probably honestly undesirable. Your hardware is racy, your OS is racy, the other programs on your computer are racy, and the world this all runs in is racy. Any system that could genuinely claim to prevent all race conditions would be pretty awful to use, if not just incorrect.

not true - you can have a program that is free of data races but still contains race conditions. Rust prevents data races.

No, Rust isn't.

Maybe you should read a bit more on its docs [1]. I quote:
