Editor to share with you what Rust means, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

What is Rust?

Rust is a system programming language that runs at amazing speed and avoids almost all crashes, memory chunk errors, and data contention. You may question why we need another such language, because there are already many similar languages. This article will tell you why.

Security vs. Right of control

You may have seen the map above. On one side is the C _ blank, which has more control over the running hardware, so it allows developers to optimize performance by exercising finer control over the generated machine code. However, this is not very secure, which can easily lead to memory block errors and security vulnerabilities such as painstaking vulnerabilities.

On the other side are languages like Python, Ruby and JavaScript that don't give developers much control but can create more secure code. Although this code can generate fairly safe and controllable exceptions, they do not cause memory chunk errors.

In the middle of the graph are Java and some other languages that mix these features. They provide control over the part of the hardware that is running and try to minimize vulnerabilities.

Rust is a little different, it doesn't appear on this map. It provides both security and control to developers.

Characteristics of Rust

Rust is a system programming language like CAccord +. In addition, it also gives developers fine-grained control over memory allocation. It doesn't need a garbage collector. Its operating environment runtime is very small and its running speed is close to that of running on bare metal. It provides developers with a greater guarantee of code performance. In addition, anyone who knows CCompact + can read and write Rust code.

Rust runs very fast because it is a compiled language. It uses LLVM as the back end of the compiler and can also take advantage of a lot of optimizations. In many areas, its performance is higher than that of CumberCandle +. Like JavaScript, Ruby, and Python, they are inherently safe, which means they don't cause memory chunk errors, wild pointer dangling pointers, or null pointer null pointers.

Another important feature is the elimination of data competition. Today, most computers have multiple cores, and many threads run concurrently. However, it is difficult for developers to write good parallel code, so this feature removes their worries. Rust uses two key concepts to eliminate data competition:

Ownership Ownership. Each variable is moved to a new location and prevents it from being referenced by the previous location. Each data block has only one owner.

Borrow Borrowing. Owned values can be borrowed to allow them to be used for a period of time.

Using Rust on Fedora 24 and 25

To get started, simply install the package:

Sudo dnf install rust

Sample code helloworld.rs:

Fn main () {println! ("Hello, Rust is running on Fedora 25 Alpha!");}

Compile and execute:

Rustc helloworld.rs. / helloworld

You can execute the following command on Fedora to install the test version of * *:
