WebAnother way to do this would be to have an immutable borrow of the character (maybe using a for loop by index) receive the whole Vec for something like “get_turn_actions,” after which you could apply the actions to a mutable reference to whatever characters they reference in the 2nd half of the loop body.

When you have a single chunk of memory (a slice or a vector) and you want to modify different parts of it via multiple slices, the borrow checker complains: let whole = vec! [1, 2, 3, 4, 5, 6]; let part1 = &mut whole[0..3]; let part2 = &mut whole[3..];

To accomplish this, Rust uses a borrowing mechanism. Instead of passing objects by value ( T ), objects can be passed by reference ( &T ). The compiler statically guarantees (via its borrow checker) that references always point to valid objects. the innocent - jack 1

In this Rust tutorial we learn how to borrow a value temporarily from its owner, which allows us to have multiple references to that value without breaking ownership. We also learn about referencing the memory address of a value and how to get the value at that address with the dereferencing operator.

That's close enough to maybe not matter. But if we change f32 to f64 now it's 8-bytes (by-borrow) versus 24-bytes (by-copy). For code that uses a Vector4 of f64 we're suddenly talking about 8-bytes versus 32-bytes. Ergonomics In C++ I know exactly how I'd write this.

WebSince the compiler cannot prove that you are borrowing disjoint parts of a vector, or that a function only borrows certain parts of a struct and not the whole object, it forces you to borrow the whole vector/struct to be safe. In the case of vectors, one could easily prove disjoint borrows when using constant vector indexes.

WebThe type of the values (probably i32) in your Vec implement the Copy trait, which means that they do not get moved out when indexing the vector, they get copied instead.. A Vec of such Copy types still doesn't implement Copy itself, so it gets moved into the loop. You can avoid this e.g. by writing. for i in vectors.iter() { println!("Element is {}", *i); }
