elixir how to create struct code example

Example 1: elixir struct

defmodule UserModule do
  
  # UserModule struct definition
  # Put this inside a module definition
  defstruct [:first_name, :last_name, :age]


  # functions to access the struct data,
  # horever if the struct and functions life in the same module, 
  # you can replace the module name with __MODULE__  attributte. 
  
  # Ej %UserModule{} is the same that %__MODULE__{}

  def first_name(%__MODULE__{first_name: name}),
    do: name

  def last_name(%__MODULE__{last_name: name}),
    do: name

  def age(%__MODULE__{age: age}),
    do: age

end

# For usage this, you can do (in iex for example):

> user = %UserModule{first_name: "martin", last_name: "alganaraz", age: 40}
> UserModule.first_name user
"martin"

Example 2: elixir struct example

# struct example
%__MODULE__{
	name: "apple",
	location: {40,0,1},
}
