Package helps you transform maps (ex. external data) to structs (internal data).

## Example

Define a structs:

```elixir

defmodule Product do

  defstruct name: nil

end

defmodule Cart do

  defstruct id: nil,

    products: nil

end

```

Define a transformation schema and then transform a map:

```elixir

def to_struct() do

  map = %{

    "id" => 1,

    "products" => [

      %{

        "name" => "milk"

      },

      %{

        "name" => "potato",

      }

    ]

  }

  schema = %Cart{

    products: [%Product{}],

  }

  ToStruct.transform(schema, map)

end

```

Result: 

```elixir

 %Cart{

  id: 1,

  products: [

    %Product{name: "milk"},

    %Product{name: "potato"}

  ]

 }

```

## Installation

```elixir

def deps do

  [

    {:to_struct, "~> 0.1.0"}

  ]

end

```
