golang turns to rust

Recently, more and more developers have begun to turn their attention from Go to Rust. Why does this happen? This article will go into depth and give some useful suggestions and experiences.

1. Comparison between Go and Rust

Go and Rust are both programming languages, but their design ideas and application scope are very different.

Go is characterized by simplicity, efficiency, security, concurrency capabilities and its powerful standard library. Go code is easy to write, easy to maintain, and is widely used on the server side.

However, since Go is designed for large-scale concurrent environments, it has some imperfections or even flaws in some aspects. These issues have been widely discussed in the Go community. For example, issues such as Go language version management, lack of generic support, and lack of polymorphism have all been criticized.

As a controllable and safe system programming language, Rust can meet the requirements for performance, concurrency and code complexity. Rust's memory management is safer than C and C. Its leading type system can avoid many C/C memory errors and improve the maintainability of the code.

In addition, Rust has excellent performance in type safety, parallelism, asynchronous and generic programming, and can support a wide range of applications, from using command line tools to building high-performance server-side applications.

Although Rust is not perfect, it can indeed perfectly complement Go's shortcomings in some cases. In addition, the Rust community is extremely active and continues to expand and improve its ecosystem, which is one of the reasons why many developers turn to Rust.

2. Suggestions for switching to Rust

When you decide to switch from Go to Rust, you need to consider the following points:

1. Learning Curve

Because Rust’s syntax is relatively complex, its learning curve may be relatively long. But at the same time, Rust is also extremely productive, so you can accelerate your learning by reading Rust's official documentation, participating in open source projects, and understanding and practicing Rust's best practices.

In addition, some developers who have switched from Go to Rust suggest that they can master the basics of Rust by trying some smaller projects, and gradually master more difficult tasks.

2. Actual scenarios for using Rust

Some developers who switch from Go to Rust suggest that they need to have an in-depth understanding of the actual usage scenarios of Rust before switching to Rust. Rust is mainly used for system programming and the development of high-performance general tools, such as operating systems, databases, compilers, etc. If your programming tasks are not related to this, Rust may not be a good choice.

3. Things to note when dealing with memory

Unlike Go, Rust’s memory management uses the concepts of borrowing and ownership. This approach ensures correct memory handling, but requires additional effort to keep the code valid. Therefore, when using Rust, you need to pay attention to how to maximize the use of these features to deal with memory.

3. Summary

Although Go has excellent performance for large-scale server-side applications and concurrent environments, Rust’s type safety, memory safety, and concurrency capabilities make it in some other fields Perform better. For those who want to develop high-performance general-purpose tools, operating systems, or compilers for system-level programming tasks, Rust may be a better choice.

Although switching from Go to Rust requires a learning curve, you can gradually improve your abilities by reading Rust's official documentation, participating in open source projects, understanding best practices, and trying some smaller projects. In addition, proficiency in memory management is also key to using Rust.
