Use the into_iter() function when you want to move, instead of borrow, your value. clone() function, this is a sign that you probably want to use. If you find yourself running into does not live long enough, move errors or using the. iter() is short-lived, so we can move or use our original value afterwards. I try to be very concious and deliberate about when I move resources and default to borrowing (or referencing) first. sort_by() provide no immutable alternative. iter_mut() often, but sometimes functions like. This means we need the ability to mutate team in order to sort. The sort_by() function performs the sorting of the Vector/slice in place. Here we are using a mutable reference to sort the list of players on each team by highest score. Let us write a simple map/reduce example: fn use_names_for_something_else(_names: Vec) ", teams_in_score_order) Use the iter() function if you want to iterate over the values by reference. This means that calling v.iter() will create a struct that borrows from v. It is important to note that this Iter type only has a reference to T. This creates an Iter type and it is this Iter type that implements the Iterator trait and allows us to call functions like. We can call v.iter() on something like a vector or slice. Let us take a journey through the world of iterators and figure out the differences between iter() and into_iter() in Rust.

If you do not realize both of these functions exist or that they do different things, you may find yourself fighting with the compiler to get your code to work. Depending on which tutorial or example you see first, you call. In Rust, you quickly learn that vector and slice types are not iterable themselves.
