The command "rustc -g ${filename.rs}" is used to compile a Rust source file with debugging symbols enabled.

Here's a breakdown of the command:

• "rustc": This is the Rust compiler command.
• "-g": This flag enables the generation of debugging symbols during compilation. Debugging symbols contain additional information that allows developers to debug the code more effectively.
• "${filename.rs}": This is a placeholder for the name of the Rust source file you want to compile. You need to replace "${filename.rs}" with the actual filename and its extension (e.g., "main.rs").

In summary, when you run this command with the appropriate file name, it will compile the corresponding Rust source file with debugging symbols enabled, allowing you to debug the code later if needed.
