#RUST FOR WINDOWS PROGRAMMING CODE#
If there is no code in your link, it probably doesn't belong here. Just because it has a computer in it doesn't make it programming.That means no image posts, no memes, no politics.Please keep submissions on topic and of high quality.Using an external library with C++ can be an issue, especially if you’re targeting multiple operating systems./r/programming is a reddit for discussion and news about computer programming Documentation for Rust is on a whole other level compared to any other language everything can be found at. Using a package is as simple as adding a line to the cargo.toml, Rust's config file. The official package manager in Rust is called Cargo. The areas where Rust definitely beats C++ and many other languages are package management and documentation. This means that even if we know that some code is safe to execute, Rust might still not allow it unless we use unsafe Rust. Rust’s compiler is very conservative in its checks, meaning that it prefers to check and block a few valid programs/operations rather than allow many unchecked operations. You lose the safety guarantees a safe Rust compiler gives you, but you gain the ability to interact with the low-level aspects of the operating system/hardware. Working in Unsafe Rust is like telling the compiler to trust you and skip some of the checks it provides. fn hello_v1 ( ) -> & str Īnother “version” of Rust called Unsafe Rust is more similar to C++. Here is an example of returning a reference to a string (&str) from a function and using it in another (main) function. Because all data lives in its own scope/context, once we move out of it, Rust will look at all of the data inside that scope and deallocate it. This is called borrowing in Rust, and that’s what makes Rust memory safe. And even then, we need to explicitly tell the compiler how we want to use that data. Rust will not let us access that data outside of that scope unless we explicitly say so. This is where ownership comes in as mentioned before, a context or function can hold or own data, meaning the data lives in the function’s scope.

At least not so easily, as the Rust compiler will let you know during compile-time that you have an error that needs to be handled. The Rust compiler keeps track of what function or what context holds what data at any given moment, so something like this most likely would not happen. This leaves you with a dangling pointer, and if you are not mindful, you could accidentally try to use that pointer again, and you will end up with some unexpected behavior. Then you call another function on that same reference, the code works, and everything seems fine, but little do you know the first pointer (returned from the function) has now been freed. Because of this, you do not have to keep track of dangling pointers or references to parts of memory, which, if left unchecked, could leave you with segmentation faults or memory leaks.įor example, in C, you have a function that returns a reference/pointer to some data. In Rust, the compiler keeps track of which data “lives” in which scope or context. Rather than re-running your application and trying to replicate an error that happened, you can spend more time writing the correct code. As your code compiles, you will get compile type checking, and the compiler will let you know if you have any unhandled errors. Rust is a statically typed language, unlike JS, Python, Ruby, or Objective- C. Thanks to these concepts, many errors in Rust are compile-time errors rather than runtime errors. These concepts might seem foreign if you have not seen them explicitly as you will in Rust. To achieve this, it introduces some new concepts, like ownership, borrowing, and lifetimes, which are the main things that keep Rust memory safe. Rust aims to be memory-safe, thread-safe, fast, and secure. As mentioned before, Rust is an open-source systems programming language.
