Struct Implementation

Method to struct -

• added in the impl block
• always takes self as its first argument

Here, the method area takes &self as its first argument. Here &self is shortcut to &self: Self.

A method can -

• Borrow a non-mutable reference of self (&self)
• Borrow a mutable reference to self (&mut self)
• Take ownership of self (self)

Method call

Rust methods can be invoked using the syntax type_instance.method_name. Unlike C/C++ it does not have the -> operator. Rust uses automatic referencing and dereferencing. It uses the self argument on the method to determine the correct calling syntax.

Associated Functions

Functions in the impl block without the first parameter as self is an associated function. Invoked by type::method_name syntax. It can use Self alias in it.

Multiple impl blocks

Each struct is allowed to have multiple impl blocks.
