Fields§
§ident: Ident
Name of the variant.
hir_id: HirId
Id of the variant (not the constructor, see VariantData::ctor_hir_id()
).
def_id: LocalDefId
§data: VariantData<'hir>
Fields and constructor id of the variant.
disr_expr: Option<&'hir AnonConst>
Explicit discriminant (e.g., Foo = 1
).
span: Span
Span
