चरैवेति, चरैवेति - Charaiveti, Charaiveti - keep walking...

because the motion is the life - we need to move on to keep the balance of life...

  


We must not stop.

  


The movement is essential.

  


Life is like a bicycle

  


The moment it stops - the balance goes for a toss

  


Life is like a stream.

  


The moment the flow of the stream is lost, all sorts of fungi pollute the water - and the water becomes dirty and ceases to be a potable one.

  


So, we have to keep moving all throughout our lives - physically - spiritually - and metaphorically - we must not stop the movement - because the 

  


Ultimate Stop comes with Death.

  


So, here we go...

  


After C++, Java and Python...

  


my first program in Rust delving into trait - which is like an interface in Java or an abstract class of C++...

  


In Rust.... I trust....

  


## Source Code:

  


trait Animal {

fn make_sound(&self);

fn wag_tail(&self){

println!("I don't have a tail...");

}

}

  


struct Human{}

impl Animal for Human {

fn make_sound(&self) {

println!("Human is speaking...");

}

}

  


struct Dog {}

  


impl Animal for Dog {

fn make_sound(&self) {

println!("Dog barks...");

}

fn wag_tail(&self) {

println!("The dog is waging it's tail");

}

}

  


fn main() {

let dog = Box::new (Dog {});

dog.make_sound();

dog.wag_tail();

let man = Box::new (Human {});

man.make_sound();

man.wag_tail();

}

  


# The output:

  


Dog barks...

The dog is waging it's tail

Human is speaking...

I don't have a tail...
