}
Expand description
A macro call, like vec![1, 2, 3]
.
Use tcx.item_name(macro_call.def_id)
to get the macro name.
Even better is to check if it is a diagnostic item.
This structure is similar to ExpnData
but it precludes desugaring expansions.
Fields§
§def_id: DefId
Macro DefId
kind: MacroKind
Kind of macro
expn: ExpnId
The expansion produced by the macro call
span: Span
Span of the macro call site
