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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
