![]() Take a reference to the data contained inside the box so the contents can be borrowed again. Println!("Destroying box that contains ", borrowed_i32) Here is a sample of the borrowing concept from the official Rust page: // This function takes ownership of a box and destroys it Rust’s other strengths include excellent documentation, helpful compiler error messages, and a friendly community. The Rust standard library also provides smart pointer types, Mutex and Arc, for safe use in concurrent contexts. Threads can communicate with each other using directional channels. Rust implements threads in a 1:1 model, meaning that a program uses 1 operating system thread for 1 language thread. As a result, developers can fix the code while working on it and avoid introducing potential bugs in production. Using ownership, borrowing and type checking helps detect concurrency errors at compile time, instead of runtime. You can have one or more immutable references to a resource OR exactly one mutable reference.A borrow must last for a scope no greater than that of the owner.The program will not compile if any of the rules are broken.īorrowing, or the act of creating a reference, also has strict rules that help prevent data races: When the owner goes out of scope, the value will be dropped.Each value in Rust has exactly one owner. ![]() Memory management is governed by a set of rules that the compiler checks: Ownership is a distinct feature that enables Rust to make memory safety guarantees without the need for a garbage collector. The Rust compiler generates with LLVM-Tools platform independent LLVM-IR code (IR stands for intermediate representation) and then native machine code for the target platform. Rust is memory-safe, thread-safe, fast, and memory-efficient, with no runtime or garbage collector. How is Rust different from other programming languages? Since 2021, Rust has been stewarded by the Rust Foundation, a non-profit organization that nurtures the Rust ecosystem and provides assistance to the group of maintainers in charge of overseeing and advancing the project. Rust grew in popularity and is in the top 20 programming languages according to the TIOBE index. In 2009, Mozilla began sponsoring the project and in 2010 they officially announced it. ![]() Rust’s development began in 2006 as a personal project of Graydon Hoare, while he was working at Mozilla Research. Rust is a general-purpose, multi-paradigm, compiled, strictly statically typed programming language designed for memory safety and performance.
