Mappable

Simple module that provides unified, simple interface for converting between different dictionary-like data types in Elixir:

  • maps
  • structs
  • keyword lists

Examples

Use Mappable.to_map map, keys: :strings to convert anything to map with string keys recursively:

%{:foo => :bar}
|> Mappable.to_map(keys: :strings)
=> %{"foo" => :bar}

Use keys: :atoms to do the same but use atom keys:

%{"foo" => %{"bar" => :baz}}
|> Mappable.to_map(keys: :atoms)
=> %{:foo => %{:bar => :baz}}

Convert anything to struct easily by matching keys:

%{"id" => 1, "email" => "jack.black@example.com"}
|> Mappable.to_struct(User)
=> %User{id: 1, email: "jack@black@example.com"}

Convert anything to keyword list with:

%{"bar" => :foo, "foo" => :bar}
> Mappable.to_list
=> [bar: :foo, foo: :bar]

Installation

If available in Hex, the package can be installed by adding mappable to your list of dependencies in mix.exs:

end
