[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
