source · [−]

pub struct Variant<'hir> {
    pub ident: Ident,
    pub id: HirId,
    pub data: VariantData<'hir>,
    pub disr_expr: Option<AnonConst>,
    pub span: Span,
}

Fields

ident: Ident

Name of the variant.

id: HirId

Id of the variant (not the constructor, see VariantData::ctor_hir_id()).

data: VariantData<'hir>

Fields and constructor id of the variant.

disr_expr: Option<AnonConst>

Explicit discriminant (e.g., Foo = 1).

span: Span

Span
