Developers : 40-Handling Result and Error Parsing in Rust using the ? Operator

💻 Handling Result and Error Parsing in Rust using the ? Operator 💻

In Rust, the ? operator simplifies error handling by propagating errors automatically. Instead of using manual pattern matching or combinators to unwrap results, the ? operator can be placed after expressions that return a Result type. If the operation is successful, it returns the Ok value, but if an Err is encountered, it immediately returns the error from the calling function. This operator greatly reduces boilerplate code and makes error propagation seamless and readable, especially in functions that deal with multiple potential failures.

📋 In this video, you’ll learn:
