Error Handling is a process that helps to identify, debug, and resolve errors that occur during the execution of a program. It helps to ensure the smooth functioning of the program by preventing errors from occurring and allowing the program to continue running in an optimal state. Error handling is a built-in [enum] in the Rust standard library. It has two variants Ok(T) and Err(E) in Rust. It can be used as a return type for a function that can encounter error situations.
