Generics in Rust

Example 1:

 #[derive(Debug)]  
 struct Point<T, U, V> {  
   x: T,  
   y: U,  
   z: V,  
 }  
   
 fn main() {  
   let point1 = Point{  
     x: 1,  
     y: 1,  
     z: 1.0,  
   };  
     
   let point2 = Point{  
     x: 1.0,  
     y: 1.0,  
     z: 1,  
   };  
     
   let point3 = Point {  
     x: 'x',  
     y: 'y',  
     z: 1,  
   };  
     
   println!("{:?}", point1);  
   println!("{:?}", point2);  
   println!("{:?}", point3);  
 }  

Example 2:

 #[derive(Debug)]  
 struct Point<T> {  
   x: T,  
   y: T,  
 }  
   
 impl<T> Point<T> {  
   fn x(&self) ->&T {  
     &self.x  
   }  
 }  
   
 fn main() {  
   let p = Point {x: 5, y: 10};  
     
   println!("{:?}", p.x());  
 }
