From the perspective of Go developers, Rust

As an experienced Go developer, I have always been curious about emerging programming languages, especially those known for their performance, reliability, and concurrency. Rust， A system programming language known for its speed and safety naturally caught my attention. After conducting in-depth research and trying to use Rust for a period of time, I would like to share some advantages and challenges of Rust from the perspective of Go developers.

The charm of Rust lies in Memory security mechanism

One of the most striking features of Rust is its powerful memory security mechanism, which is achieved through concepts such as ownership, borrowing, and lifecycle. Unlike Go’s garbage collection mechanism, Rust can capture memory management errors such as dangling pointers, data contention, and memory leaks at compile time. This not only improves the reliability of the program, but also reduces the possibility of runtime crashes.

Here is a simple example:

let s1 = String::from("hello");
let s2 = s1;      // println! ("{}", s1); //Compilation error, ownership of s1 has been transferred to s2      
println!("{}", s2);

In this example,s1The ownership has been transferred tos2Therefore, we will attempt to use it in the subsequent codes1It can lead to compilation errors. This strict rule effectively avoids issues such as hanging pointers and memory leaks.
