Allow decoder as option to be a function #207

rauann · 2022-04-25T11:32:32Z

This PR adds a change that allows the option as value to be a function which is useful when you want decode to structs dynamically based on the json received:

person = ~s({"name":"Devin Torres"})
contact = ~s({"email":"test@dev.com"})

as = fn
   %{"name" => _name} -> %Person{}
   %{"email" => _email} -> %Contact{}
end

Poison.decode!(person, %{as: as})
# %Person{name: "Devin Torres"}

Poison.decode!(contact, %{as: as})
# %Contact{email: "test@dev.com"}
