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<AnonConst>
Explicit discriminant (e.g., Foo = 1
).
span: Span
Span

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.
