Mason uses superpowers to coerce maps into structs. This is helpful e.g. when you interface a REST API and want to create a struct from the response.
defmodule User do
defstruct [ :user_id, :created_at ]
def masonstruct do
%{
createdAt: &({ :created_at, elem(DateTime.from_unix(&1), 1) }),
userId: &({ :user_id, &1 })
}
end
end
response = %{ "userId" => 123, createdAt: 1456749030 }
Mason.struct User, response # %User{created_at: #DateTime<2016-02-29 12:30:30Z>, user_id: 123}
- coerce to Elixir's built-in types from strings
- dynamically coerce values (e.g. timestamps to
DateTime
s) - map keys (e.g.
createdAt
tocreated_at
) - convert string keys to atoms (e.g.
..., "age" => 29, ...
to..., age: 29, ...
) - convert lists
The package can be installed by adding mason
to your list of
dependencies in mix.exs
:
def deps do
[
{:mason, "~> 0.1.0"}
]
end
