Monomorphization The Rust Way

What is Monomorphization?

It’s like making copies of a tool so each copy fits a specific job.


Imagine This:

You have a magic hammer 🛠️ that can fix anything — bikes, cars, phones, even shoes! That’s cool, but every time you use it, you have to wait while it changes shape to fit the job. That takes time ⏳.

Now, instead of one magic hammer, what if you made special hammers for each job:

  • A bike hammer 🚲
  • A car hammer 🚗
  • A phone hammer 📱

Now, fixing is faster — just grab the hammer made for the job.


In Code:

You write one function that works for any type (like the magic hammer).

But before your program runs, the computer creates a version of the function for each type (like making the special hammers).

Why It’s Cool:

✅ Your program runs faster.

❌ It might take a little more space (because of the copies).
