[][src]Enum syntax_pos::hygiene::ExpnKind

pub enum ExpnKind {
    Root,
    Macro(MacroKindSymbol),
    Desugaring(DesugaringKind),
}

Expansion kind.

Variants

Root

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

Macro(MacroKindSymbol)

Expansion produced by a macro. FIXME: Some code injected by the compiler before HIR lowering also gets this kind.

Desugaring(DesugaringKind)

Desugaring done by the compiler during HIR lowering.
