Where Does Rust Place Compiled Files Stored

When you compile a Rust program, the output is stored in a specific location, which can vary depending on several factors. Understanding where these compiled files are stored is crucial for managing your project effectively. Let’s delve into the details of where Rust places compiled files and how you can locate them.

Default Compilation Directory

The default directory where Rust stores compiled files is often the same directory as the source file. This is the case when you use the `rustc` command to compile a single file. For example, if you have a file named `main.rs` in the current directory, running `rustc main.rs` will compile it and store the output in the same directory.

Using Cargo for Compilation

Cargo, Rust’s package manager and build system, handles the compilation process for projects with multiple files. When you run `cargo build`, Cargo compiles the entire project and stores the output in a specific location within your project directory. By default, this location is a directory named `target` in the root of your project.

Here’s a breakdown of the `target` directory structure:

The `debug` directory is used for development and testing, while the `release` directory is used for production. You can switch between these configurations using Cargo commands like `cargo build` for debug and `cargo build –release` for release.

Custom Compilation Directories

While the default behavior is to store compiled files in the `target` directory, you can specify a custom directory for compilation using the `–out-dir` flag with the `rustc` command or the `build` command with Cargo. This allows you to organize your project’s files in a way that suits your needs.

For example, to compile a Rust program and store the output in a custom directory named `custom-target`, you can use the following command:

rustc --out-dir custom-target main.rs

Similarly, with Cargo, you can specify a custom directory using the `–out-dir` flag:

cargo build --out-dir custom-target

Locating Compiled Files

Once your program is compiled, you can locate the compiled files by navigating to the specified directory. For example, if you compiled your program using Cargo and stored the output in the `custom-target` directory, you can find the compiled files by running the following command in your terminal:

cd custom-target

This will take you to the `custom-target` directory, where you can find the compiled files for your program.

Conclusion

Understanding where Rust places compiled files is essential for managing your Rust projects effectively. By default, compiled files are stored in the `target` directory within your project, but you can specify a custom directory using the `–out-dir` flag. Knowing this information allows you to organize your project’s files and locate compiled files easily.
