Lyrics

[Verse 1]
When your data needs to show itself
Or transform from one type to another shelf
Rust has traits that work like magic spells
Four common ones that serve you well

From converts types with grace and ease
Into transforms with guarantees
Display shows what the user sees
Debug prints for developers please

[Chorus]
From and Into, Display and Debug too
These are the traits that see you through
From and Into, Display and Debug crew
Converting and printing, that's what they do

[Verse 2]
From trait takes one type, makes it new
Like string slices turning into String for you
Into is the flip side of the same coin
Where the destination type you join

When you call "into" on your data
From trait does the work, no extra strata
One trait implements, the other's free
That's how Rust keeps things clean, you see

[Chorus]
From and Into, Display and Debug too
These are the traits that see you through
From and Into, Display and Debug crew
Converting and printing, that's what they do

[Bridge]
Display for the users, clean and neat
No extra brackets, output's sweet
Debug for developers, shows it all
Curly braces help you when you fall

println macro with different faces
"left brace right brace" for Display cases
"left brace colon question right brace" for Debug traces
Both help you see what your code embraces

[Verse 3]
Implement these traits upon your structs
Display writes the format that constructs
A pretty string for end users to read
Debug shows all fields when you need

These four traits work in harmony
Converting types and showing clearly
Master them and you will find
Rust development peace of mind

[Chorus]
From and Into, Display and Debug too
These are the traits that see you through
From and Into, Display and Debug crew
Converting and printing, that's what they do

[Outro]
From and Into for conversion flow
Display and Debug help your data show
Four common traits that you should know
Watch your Rust programs smoothly grow
