8/17/2023 0 Comments Rust programming language uses![]() With it, we can pass to functions, references to variables and access underlying data, and even mutate it (as we’ll see in the handle_input function).Here at ACV Auctions we use many programming languages to deliver our services to our customers, whether it be Python, Java, C#, Go, JavaScript, Kotlin, and Swift to name a few.Īll of these languages have their tradeoffs in how they allow a software engineer to solve problems. How do we pass arguments into functions and still reuse the variables? Rust has some sort of pointer-like magic called Borrowing. This time we’d have no errors since the underlying data is copied to bye and ownership of bye isn’t performed. Using the code above, we can solve this problem by performing explicit deep copying like so: let hello = String::from(“hello”) This is because, due to the use of String::new(), the size of hello is known at compile-time, therefore, there’s no deep or shallow copying here. hello on the other hand, has no problems with this. The new variable takes ownership of bye and bye ceases to exist. bye ceases to exist the moment it is used somewhere else. This program calculates the love compatibility of a male and a female with their names as input: function handle_input(arg: memory_address_to_store_input) ”, greeting, hello, bye) Īgain, as expected, this code won’t compile. Rust way of doing things diverges from the other languages, hence the need for pseudocode to outline steps in our code. Here we’ll be using a basic formula to derive compatibility percentages: (length_of_shorter_name/length_of_longer_name) × 100 Pseudocode: ![]() ![]() Perhaps you remember the popular “flames” method. We all had our own shares of love plays while young. Building A simple love calculator in Rust You also get a linter: clippy, and a nice way to run tests for your code. The latter is an abstraction that provides common tools needed by developers to organize their code and other external libraries. The former is the standard Rust tool for compiling and executing your code. Head to the official website and follow the steps.įrom your CLI, confirm your installation with rustc –-version and cargo –-version The Borrow Checker, which most Rust developers would fight every now and then, ensures memory safety, a foreign concept to core C and C++. In place of Garbage-Collection, Rust programming language allows the developer to make the choices of memory management with concepts such as Ownership and Borrowing. Rust programming language brings to the table, new and opinionated ways of doing things.Ĭoncepts such as the Borrow Checker sound new to most developers coming from Garbage-Collected languages such as Go, Javascript, and Python. It is no wonder that the Rust language has come a long way given its age. With a five-year record of the world’s most loved programming language on stack overflow’s index 2020: ![]() ![]() It is largely seen by developers as a replacement for the mature C and C++, languages as old as they are powerful.Ĭreated by Graydon Hoare at Mozilla Research with inputs from Dave Herman and Javascript creator, Brendan Eich. Rust is a systems programming language with a focus on performance, memory safety, and safe concurrency. ![]()
