Build the Rust compiler and explore the language's core source code
If you want to write low-level code for operating systems or embedded chips while preventing critical bugs like memory leaks or concurrency errors at the compile stage, this repository is your starting point. It contains the core source code for the Rust language, including the compiler, standard library, and tools for the developer experience. You can use this repository to understand the language's internal structure or build and use the latest version of the compiler directly.
Design for performance and safety
Rust provides fast execution speed and memory efficiency, making it suitable for critical services or embedded devices. Thanks to its rich type system and ownership model, memory safety and thread safety are guaranteed, and many bugs are discovered at compile time. This design contributes to reducing runtime errors. Additionally, integration with other languages is easy, giving it an advantage in system-level tasks.
Tools for developer productivity
Beyond just the language, tools that boost productivity are provided. Cargo, the package manager and build tool, handles project management and dependency resolution. rustfmt automatically formats code, and Clippy acts as a linter to catch potential issues. rust-analyzer supports code completion and error diagnostics in editors, and the compiler itself is designed to provide clear diagnostic messages.
Source build and contribution guide
General users are recommended to follow the installation guide in the official documentation. However, if you need to research the compiler's internal structure or apply specific patches, you can build the source directly from this repository. The INSTALL.md file contains detailed instructions on the source build process. To understand the compiler's architecture and start contributing, refer to rustc-dev-guide.

When to open this repository
This repository is more suitable for people who want to research the language itself or participate in compiler development rather than developers who simply use the Rust language. You do not need to clone this repository for general application development; using the official installation tools is more efficient. However, if you want to dig into Rust's internal workings or fix compiler bugs, this source code is essential material. Because it has a dual license structure, you should verify legal conditions before using it in commercial projects.
