elixir new structs
To create a new Elixir project with structs, you can use the mix new
command followed by the project name. Here's an example:
$ mix new my_project
This will create a new Elixir project named my_project
in a directory with the same name.
To define a struct in Elixir, you can use the defstruct
macro. This macro is used to define a module that represents a struct and its fields. Here's an example of how to define a struct named Person
with name
and age
fields:
defmodule Person do
defstruct [:name, :age]
end
Once you have defined a struct, you can create instances of it by using the new
function. Here's an example:
person = %Person{name: "John", age: 30}
In this example, we create a new instance of the Person
struct with the name "John" and age 30.
You can access and update the fields of a struct using the dot notation. Here are some examples:
name = person.name
# Access the name field of the person struct
updated_person = %{person | age: 35}
# Update the age field of the person struct and assign it to a new variable
