[Concept Entry] Rust: Ownership #5052

Open rescgutierrez opened 3 weeks ago

rescgutierrez commented 3 weeks ago

Reason/inspiration (optional)

Many of Rust's advantages regarding security, speed, and avoidance of general errors in code are related to how it's compiler checks variable ownership. In specific, Rust ownership rules allow to leave aside a garbage collector for memory cleanup, prevents programmers from leaving and using dangling pointers, among other examples.

There's a complete chapter discussing ownership in Rust's main online book, that begins with "Ownership is Rust’s most unique feature and has deep implications for the rest of the language." The link to the book: https://rust-book.cs.brown.edu/ch04-00-understanding-ownership.html

It is not only the most unique feature of the language, but also the one that is harder to get used to. Because of this there are ownership related excercises at the end of many chapters.

The page for this concept should be ownership.md in docs/content/rust/concepts/ownership. It should include a few examples of unsafe code, and how Rust ownership rules prevent its compilation. The examples should be the minimum necessary to show how Rust is different from other languages regarding code safety, and refer readers to the book for more details. A full explanation of the concept and its application could be very lengthy.

Sounds good, @rescgutierrez. Let's implement the following:

It should include a few examples of unsafe code, and how Rust ownership rules prevent its compilation. The examples should be the minimum necessary to show how Rust is different from other languages regarding code safety, and refer readers to the book for more details.

Let's leave this out since it can be very lengthy:
