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: 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.
