What's the difference between self and Self in Rust?

In Rust, self and Self serve different purposes and are used in different contexts within the language.

self

• Instance Reference: self is used as the first parameter in method definitions to refer to the instance of the struct or enum on which the method is being called. It is analogous to this in other object-oriented languages like JavaScript or Python.
• Ownership and Borrowing: When used in method signatures, self can take different forms to indicate ownership and borrowing:
  • self: Takes ownership of the instance.
  • &self: Borrows the instance immutably.
  • &mut self: Borrows the instance mutably.
• Example:
  rust Copy

  struct MyType;
  
  impl MyType {
      fn consume(self) {
          // Takes ownership of the instance
      }
  
      fn borrow(&self) {
          // Borrows the instance immutably
      }
  
      fn borrow_mut(&mut self) {
          // Borrows the instance mutably
      }
  }

Self

• Type Alias: Self is a type alias for the type that is currently being implemented. It is used within impl blocks and trait definitions to refer to the type for which the methods...
