1. Don't call rustc directly, do it via cargo 2. You don't have to declare the type of a variable in most cases 3. Mutable variables are stored on the stack. When you need dynamic size, then you use Box which indicates that the variable is stored on the heap.

About #3, there is more to it. A string is dynamic so using Box is pointless since String::from() returns a pointer to a string that goes onto the stack while the string itself goes into the heap. Lots of weird exceptions go into it to make it difficult to explain that can only be solved on a per case basis per type

@pedrodesu

I'd propose just some minor changes 1.1. As was already pointed, rustc makes complete sense when you merely want to use Rust's compiler, for instance for a simple file or any environment where you don't need the notion of a "full project" with package management. Otherwise cargo is indeed more suited. 3.1. A Box is a smart pointer. The value it refers to, of type T, is indeed stored in the heap, but the structure itself, Box, which is the value returned (the "variable") when instantiating a new boxed value (the "pointer" to the memory in the heap), is stored in the stack.

Good video overall, but a major mistake: YOU decide what values live on the stack or heap, NOT whether the value is immutable or not. I can have: struct Foo { bar: i32 } let mut x = Foo {bar:42};" and "let x = Foo{bar:32}", both are gonna live on the stack, unless I heap-allocate them explictly like I do in C/C++. I think what you're talking about is that you can't have unknown-sized values on the stack. Like you can't declare an array with non-const size, because that would depend at runtime, which isn't allowed, you'd have to heap-allocate that array.

Mutability doesn't mean it's stored in the heap. It is stored in the heap if the size cannot be known at compile time such as Vector, etc . In order to make `hello` variable heap allocated, you would have to wrap it in a smart pointer

Your videos are amazing!!! Sometimes are even better than a "getting started" of 30 minutes tutorials 🔥

Nice video! Just a heads up tho making a variable mutable doesn't make it heap allocated. Allocation explicitly happens when using types like Vec, Arc, Rc, Box, String, etc.

@danielegvi

2 жыл бұрын

Practically, heap allocation is implicit. Any third-party data structure might internally use boxes or vecs, it’s up to their documentation to tell you so. As long as you’ve got full support for std, that’s just left as an implementation detail.

Pretty good overview. Just a little nit pick for @0:58: Mutability is not a deciding factor for a value placed Heap vs. stack. In Rust, it cannot because mutability is an attribute of the handle, not of the value. Now, dynamically sized elements are placed on the Heap, and the developer can force anything to be on the Heap by using constructs like Box. Anyway, great video. Hope many will look at Rust.

0:41 Outstanding video! Just to amplify, for newbies: Rust uses a "middle path" to be both performant and safe (from a bug standpoint, which implies a _security_ standpoint). This combination is key to understanding its popularity. The key to learning Rust is to accept that the Borrow Checker will hound you like a vicious dog (but it has your back).

I find the C++ „Shooting in the foot“-part very funny. And I say that as someone who really enjoys using C++. But there a few things i‘d like to mention: The code shown in 0:46 is C-Style. In C++ you normally simple allocate memory using the „new“ keywoard. Also there are several ways to easily deal with dynamic memory, e.g. using STL containers or smart pointes. You will never have to worry about Memory Leaks anymore if you use them.

super cool! it's also good to mention that rust compiler errors are SUPER helpful and, most often, precise.

I'm half way theough the book, but I'd really appreciate a Rust tutorial by Fireship.

0:59 may or may not. We don't specifically have objects in rust. Most heap allocations are carried out with Box.

Great and long-expected video! Just some notes which may make it better: Except for the already mentioned /mut not requiring heap/ error. It is also worth mentioning that the type inference is smart enough to make it not needed to place explicit type annotations (as on 1:43) in most cases. The reason why it has to be used in this particular example is that `collect()` works on arbitrary *target* types and thus it need a type hint into what to collect the data. Also, to be fair, the screenshot at 1:27 has not got much to do with borrowing checker (there may be better examples, I guess). Also, the preferred way to build binaries is `cargo build` instead of `rustc`. So I guess (just my personal opinion) that it may be reasonable to have the video updated/reuploaded with these patches so that it gives a better image of the language in general (and not get used in holywars as an argument, haha).

Would love more of Rust in any form on this channel. Currently learning the fundamentals of it, but I hope to learn how it is used in WebAssembly!

"Future Linux Kernel?". Your prediction was on point!! Well not the entire kernel is being replaced with Rust but they are now adding Rust support in next version of it's Kernel. v6.1

Good video but things are only on heap when you explicitly make them on heap by wrapping them in a heap container like Box or Rc. Mutable values can be on stack as long as their size is known at compile time, this is possible even if you reassign the variable. If you have something stored like a polymorphic type like a trait and you want to store a struct that implements that trait you would need to store it in a Box (with dynamic dispatch(dyn)) since the size of a value like that can't reliably be known at compile time. Also to compile a rust project with dependencies and utilize the build system you need to use cargo (eg. cargo build, cargo run) instead of rustc.

Yes I too would love to see the detailed tutorial from basics to advanced. You explain things very good.

No half-competent C++ programmer would routinely use malloc/free, or even new/delete when it can be easily avoided. Fun fact: C++ actually has automatic memory and resource management. Well, kind of, at least. It's called RAII. The problem is that it's not enforced, and sometimes tricky to get right. This is where Rust and its borrow checker comes in - it picks up C++' idea of automatic resource management, makes it mandatory and goes out of its way to keep you from getting it wrong.
