Expandable values
Plain values
Sequence type
All List-like structures are the same, so we parsed them into ElmSequence type. However we would like to keep the information about which
type the sequence was.
Determines whether value has any nested childrens.
Elm values that are parsed can be either plain values like Strings and Bools, or they can be expandable values like Records, Dicts etc.
Expandable values has bool as their first parameter, which is used to indicate whether they are expanded or collapsed. This is used in UI to show either the short version of the expandable value or the full, expanded one. It is part of the parsed type because performance of adding it later on large models is really costly. This might change in the upcoming versions of this parser.
