Because Email is not a type alias for String, but is instead a separate

custom type, it is now impossible to mix up the argument order of the

If Email were instead defined as `type alias Email = String`, we could

|
||||
To see the difference between { extraInfo : a } and { extraInfo : Maybe Body },
|
||||
consider the difference between the "view individual Todo" page (which
|
||||
renders one Todo, including its body) and the "Todo feed" -
|
||||
which displays multiple Todos, but without bodies.
|
||||
This definition for `Todo` means we can write:
|
||||
viewTodo : Todo Full -> Html msg
|
||||
viewFeed : List (Todo Preview) -> Html msg
|
||||
This indicates that `viewTodo` requires an Todo _with a `body` present_,
|
||||
wereas `viewFeed` accepts Todos with no bodies. (We could also have written
|
||||
it as `List (Todo a)` to specify that feeds can accept either Todos that
|
||||
have `body` present or not. Either work, given that feeds do not attempt to
|
||||
read the `body` field from Todos.)
|
||||
This is an important distinction, because in Request.Todo, the `feed`
|
||||
function produces `List (Todo Preview)` because the API does not return bodies.
|
||||
Those Todos are useful to the feed, but not to the individual Todo view.

||||

|
||||
type Todo a
|
||||
= Todo Internals a
|
||||
|
||||
|
||||
{-| Metadata about the Todo - its title, description, and so on.
|
||||
Importantly, this module's public API exposes a way to read this metadata, but
|
||||
not to alter it. This is read-only information!
|
||||
If we find ourselves using any particular piece of metadata often,
|
||||
for example `title`, we could expose a convenience function like this:
|
||||
Todo.title : Todo a -> String
|
||||
If you like, it's totally reasonable to expose a function like that for every one
|
||||
of these fields!
|
||||
(Okay, to be completely honest, exposing one function per field is how I prefer
|
||||
to do it, and that's how I originally wrote this module. However, I'm aware that
|
||||
this code base has become a common reference point for beginners, and I think it
|
||||
is _extremely important_ that slapping some "getters and setters" on a record
|
||||
does not become a habit for anyone who is getting started with Elm. The whole
|
||||
point of making the Todo type opaque is to create guarantees through
|
||||
_selectively choosing boundaries_ around it. If you aren't selective about
|
||||
where those boundaries are, and instead expose a "getter and setter" for every
|
||||
field in the record, the result is an API with no more guarantees than if you'd
|
||||
exposed the entire record directly! It is so important to me that beginners not
|
||||
fall into the terrible "getters and setters" trap that I've exposed this
|
||||
Metadata record instead of exposing a single function for each of its fields,
|
||||
as I did originally. This record is not a bad way to do it, by any means,
|
||||
but if this seems at odds with <https://youtu.be/x1FU3e0sT1I> - now you know why!
