Member Functions in Rust

TL ; DR:

• A member function (or method) is a function defined for a struct. It can read and write the object's data members.

  
  

• Define methods in an impl block; the &self parameter is what lets you call them with a dot (add pub if other modules need to call them):

  struct Dog {
      pub name: String,
  }
  
  impl Dog {
      fn new(name: &str) -> Dog {
          Dog { name: name.to_string() }
      }
  
      pub fn bark(&self) {
          println!("Woof! I am {}", self.name);
      }
  }
  

  
  

• Call it on an object with the dot operator: dog.bark();
