Rust is a popular choice for software refactoring, and FreeBSD is also considering its integration

In recent years, the trend of refactoring the Rust language has swept the development circle. Rust has received widespread attention for its advantages in safety, efficiency, and maintainability. Even the Windows and Linux kernels have introduced Rust support. This makes Rust one of the most popular programming languages ​​among developers.

FreeBSD developers are also currently weighing the pros and cons of using the Rust programming language for their base systems.

According to the latest email message from the developer, The main disadvantage of including Rust in the FreeBSD base system is doubling the build time . Due to the need to compile the LLVM-based Rustc compiler and all the additional features of Rust, the system will take approximately twice as long to build as it currently does. However, developers have come up with some ways to reduce build times.

The advantage of introducing Rust is that developers can (re)write various basic components in Rust, such as ZFS daemon (zfsd), devd, WiFi user space code, etc., to replace C,And can make some tools easier to write.

The developers have not yet discussed the final result. This site attaches an email link:

In addition, Git developers are also considering introducing Rust into Git projects to reduce the risk of memory safety errors. Using Rust also comes with the challenge of using the LLVM-based rustc compiler.
