Enum rustc_span::hygiene::ExpnKind

pub enum ExpnKind {
    Root,
    Macro(MacroKind, Symbol),
    AstPass(AstPass),
    Desugaring(DesugaringKind),
    Inlined,
}

Expansion kind.

Variants

Root

No expansion, aka root expansion. Only ExpnId::root() has this kind.

Macro(MacroKind, Symbol)

Expansion produced by a macro.

AstPass(AstPass)

Transform done by the compiler on the AST.

Desugaring(DesugaringKind)

Desugaring done by the compiler during HIR lowering.

Inlined

MIR inlining
