[Verse 1]
When you need to group your data all together
Like a person with a name and age
Struct keyword starts the magic, keeps it tethered
Fields inside become your custom stage
Define the blueprint once and use it often
Each field gets its type declared with care
Your data structure's ready to be awoken
A custom type that's yours to declare
[Chorus]
Struct it up, group your data tight
Impl blocks bring your methods to life
Define once, use it everywhere
Methods live inside with impl care
Struct it up, organize your code
Impl makes your data hit the road
[Verse 2]
Instance time, you fill each field with values
Creating objects from your struct design
Use dot notation when you need to access
Each piece of data sitting in a line
But structs alone just hold your information
They need some actions to be truly great
That's where implementation comes to save you
Methods make your data participate
[Chorus]
Struct it up, group your data tight
Impl blocks bring your methods to life
Define once, use it everywhere
Methods live inside with impl care
Struct it up, organize your code
Impl makes your data hit the road
[Bridge]
Associated functions start with capital Self
Constructor patterns help you build it right
Methods take ampersand self as their first help
Borrowing the instance, keeping ownership light
Functions without self are like static calls
No instance needed, just the struct name
Implementation blocks can hold them all
Playing by the Rust ownership game
[Verse 3]
Multiple impl blocks for the same struct type
Organize your methods any way you choose
Keep related functions grouped together tight
Clean separation that you'll never lose
Your struct becomes a powerful creation
Data and behavior joined as one
Object-oriented simulation
In Rust's safe memory paradigm
[Chorus]
Struct it up, group your data tight
Impl blocks bring your methods to life
Define once, use it everywhere
Methods live inside with impl care
Struct it up, organize your code
Impl makes your data hit the road
[Outro]
From simple data to complex behavior
Structs and impls are your coding savior
Blueprint once, implement with style
Rust programming with a knowing smile
