Expand description

Expansion kind.

Variants

`Root`

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

`Macro(MacroKind, Symbol)`

Tuple Fields

0: MacroKind

1: Symbol

Expansion produced by a macro.

`AstPass(AstPass)`

Tuple Fields

0: AstPass

Transform done by the compiler on the AST.

`Desugaring(DesugaringKind)`

Tuple Fields

0: DesugaringKind

Desugaring done by the compiler during HIR lowering.

`Inlined`

MIR inlining
