pub struct MacroCall {
pub def_id: DefId,
pub kind: MacroKind,
pub expn: ExpnId,
pub span: Span,
}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: DefIdMacro DefId
kind: MacroKindKind of macro
expn: ExpnIdThe expansion produced by the macro call
span: SpanSpan of the macro call site
