 type Id {
   Id(id: String)
 }
 let res: t.Schema(Id) = typed(
     Id, 
     #(

     )
 )

pub fn validate(schema: Schema(a), obj: b) -> Result(a, String)

Takes in a schema from typed along with a mapping and returns a result of the type.

 let res: t.Schema(Id) = typed(...)
 let assert Ok(my_id) = validate(res, [#("id", "1532594324")])
 // type of `my_id` is `Id`
