Decodes a DatoCMS DAST schema.

It requires a list of items that are used within blocks, inline items and/or item links nodes. If you don't use any of those nodes in your DAST document, you can provide an empty list.

type alias ImageItem =
    { url : String
    , alt : String
    }


items : List ( ItemId, ImageItem )
items =
    [ ( itemId "123456789", { url = "https://www.datocms-assets.com/some/path.png", alt = "Some image" } ) ]


myFieldDecoder : Decoder (StructuredText ImageItem)
myFieldDecoder =
    Decode.field "value" (StructuredText.Decode.decoder items)
