File I/O and OS interactions in Rust

In Rust, File I/O is managed using the std::fs and std::io modules. These modules allow reading, writing, and manipulating files safely and efficiently. Common operations include creating, opening, reading, and writing files. Errors are handled explicitly with the Result type, ensuring robust error management.

For OS interactions, the std::env module is used to work with environment variables and command-line arguments. The std::process module allows spawning and managing processes, running commands, and handling their input/output. Rust's approach to File I/O and OS interactions emphasizes safety and explicit error handling.
