[Verse 1] When your code might fail or succeed Rust has types for what you need Option wraps what might not be Some with value, None empty Maybe you will find the key Maybe nothing's there to see Better than a null surprise Option keeps your program wise [Chorus] Some or None, that's Option's way Result's Okay or Error's day Handle failure, don't ignore Rust makes safety worth fighting for Some or None, Option's friend Result helps your code defend Against the crashes, against the breaks Explicit handling's all it takes [Verse 2] Result type has two sides too Okay when your function's true Error when things go astray Both paths handled, Rust's way Pattern matching shows the route Match expression sorts it out If let syntax keeps it clean Cleanest error handling seen [Chorus] Some or None, that's Option's way Result's Okay or Error's day Handle failure, don't ignore Rust makes safety worth fighting for Some or None, Option's friend Result helps your code defend Against the crashes, against the breaks Explicit handling's all it takes [Bridge] Unwrap will panic if you're wrong Question mark keeps code flowing strong Map and flat map transform inside Combinators are your guide Chain them up and pipe them through Functional style will see you through No more nulls or mystery crashes Your program never turns to ashes [Verse 3] When you're parsing strings to numbers Option guards against the blunders When you're reading from a file Result saves you from denial Every error has its place Every None shows missing space Compiler forces you to think Saves you from the coding brink [Chorus] Some or None, that's Option's way Result's Okay or Error's day Handle failure, don't ignore Rust makes safety worth fighting for Some or None, Option's friend Result helps your code defend Against the crashes, against the breaks Explicit handling's all it takes [Outro] No more segfaults in the night Option Result make it right Rust's type system shows the way Safe code every single day
