Developers : 22-Understanding the Unit Type in Rust

📦 Understanding the Unit Type in Rust 📦

In Rust, the Unit type () represents an empty value or nothing at all. It is commonly used as the return type for functions that don't return any meaningful value. When a function returns (), it signifies that its purpose is for side effects rather than data processing. For example, fn main() {} has an implicit return type of (), meaning it completes without returning any value. The Unit type helps express functions or operations that exist purely for their execution rather than producing output. 🛠️
