Hello,

Welcome to the forum

This may help you  
from\_struct(struct)[View Source](https://github.com/elixir-lang/elixir/blob/v1.6.5/lib/elixir/lib/map.ex#L853)

from\_struct([atom](https://hexdocs.pm/elixir/1.6.5/typespecs.html#basic-types)() | [struct](https://hexdocs.pm/elixir/1.6.5/typespecs.html#basic-types)()) :: [map](https://hexdocs.pm/elixir/1.6.5/typespecs.html#basic-types)()

Converts a `struct` to map.

It accepts the struct module or a struct itself and simply removes the ` __struct__ ` field from the given struct or from a new struct generated from the given module.

## Example

```elixir
defmodule User do
  defstruct [:name]
end

Map.from_struct(User)
#=> %{name: nil}

Map.from_struct(%User{name: "john"})
#=> %{name: "john"}

```
