[Verse 1]
In Rust there's a rule that keeps memory clean
One owner at a time for each value you've seen
But sometimes you need to just peek and not take
That's when borrowing helps for your program's sake
You use an ampersand to create a reference
No ownership transfer just temporary preference
[Chorus]
One at a time for mutable borrow
Shared or exclusive that's the rule to follow
References can't outlive what they point to
Borrowing rules keep your memory true
Check it at compile time before you run
Rust prevents the races before they've begun
[Verse 2]
Immutable borrows you can have many more
Read-only access opening that door
But mutable borrows are exclusive you see
Only one at a time is the guarantee
No mixing the two at the very same time
This prevents data races by Rust's design
[Chorus]
One at a time for mutable borrow
Shared or exclusive that's the rule to follow
References can't outlive what they point to
Borrowing rules keep your memory true
Check it at compile time before you run
Rust prevents the races before they've begun
[Bridge]
The borrow checker is watching your code
Making sure lifetimes follow the right road
When the owner goes away references must too
No dangling pointers coming through
It might seem strict but it's keeping you safe
From bugs that in other languages you'd chase
[Verse 3]
Sometimes you'll fight with the borrow checker's might
But trust in the process it's keeping things right
Split your borrows or clone when you need
These patterns will help you succeed
The compiler's your friend though it might not feel so
It's teaching you safety as your skills grow
[Final Chorus]
One at a time for mutable borrow
Shared or exclusive that's the rule to follow
References can't outlive what they point to
Borrowing rules keep your memory true
Check it at compile time before you run
Rust prevents the races before they've begun
[Outro]
Borrow with care and your code will be strong
The checker's protection will guide you along
