+# Constructors
+
+Constructors are a way to give data to an object right when it gets created. The
+object can also run functions on that data during construction.
+
+Constructors should only be used to initialize data which the object needs to
+function.

+# Constructors in rust
+
+Rust is a special case for constructors. The language itself is already
+different from most other languages in structure, especially for object oriented
+programming.
+
+Simply said, there are no constructors in rust. When you create an object, you
+have to initialize all data immediately and by yourself.
+
+You can look into the classes or instances examples to see how object
+construction is done in rust.
