Ahaha, ça me donne encore plus envie d'utiliser lib.rs.

En plus il y a un bang Duck Duck Go pour ça ! !librs

Une lib pour gérer les arguments en ligne de commande, mais plus légère que clap.

Mon “framework” web préféré en rust.

Inheritance:

Animal > Mammal > Feline > Cat   

(class)     (method)
Animal:     Eat  
Mammal:     Warm Blood  
Feline:     Meow   

(class)
Cat extends Feline  

Composition / Traits:

(trait)     (method)
Eat:        Eat   
Warm Blood: Warm Blood  
Feline:     Meow  

(struct)
Cat = Eat + Warm Blood + Meow + Eat   

Both really work out and give you the exact same results in most cases. Devil's in the details though. Composition generally* works out better if you don't > have a fixed/known understanding of the entire domain.

If we had to add a new animal that had never existed before... like a Furry. Which is not feline but can meow is also warm blooded and also eats.

In Inheritance:

Animal > Mammal > MeowerControllerManager > Feline 
                                     ^----> Furry

(class)                   (method)
Animal:                   Eat  
Mammal:                   Warm Blood  
MeowerControllerMananger: Meow   

MeowerControllerManager > Feline   
MeowerControllerManager > Furry   

When your domain knowledge is lacking or you have shifting/changing business logic, OOP will give you a hard time. If you're solving something well defined it totally works out most of the time.

In Composition:

You'd just add a new combination of your existing "traits"

Furry = meow + warm blooded + eat
