Fields

cx: &'a mut ExtCtxt<'b>monotonic: bool

Implementations

Collects all macro invocations reachable at this time in this AST fragment, and replace them with “placeholders” - dummy macro invocations with specially crafted NodeIds. Then call into resolver that builds a skeleton (“reduced graph”) of the fragment and prepares data for resolving paths of macro invocations.

A macro’s expansion does not fit in this fragment kind. For example, a non-type macro in a type position.
