Advanced concepts

Aliasing means one memory space is referenced by multiple references.

As aliasing a mutation together is the problem, rust prevent that to happen at the same time.

Ownership

In Rust, unlike C++, by default, on a function call, the ownership of parameters is transferred; the copy should be explicit (.clone()). Therefore, parameters cannot be reused after the function call.

Borrowing

Shared borrow

Cannot mutate while shared.

Mutable borrow

Cannot access while borrowed.

Can access the mutable borrowed variable.

Traits

Marker traits

• trait Send { }: Safe to send between thread: String, u32, Arc<String>
• trait Copy { }: Safe to memcpy: u32, f32,
