[][src]Enum rustc_hir::VariantData

pub enum VariantData<'hir> {
    Struct(&'hir [StructField<'hir>]bool),
    Tuple(&'hir [StructField<'hir>]HirId),
    Unit(HirId),
}

Fields and constructor IDs of enum variants and structs.

Variants

Struct(&'hir [StructField<'hir>]bool)

A struct variant.

E.g., Bar { .. } as in enum Foo { Bar { .. } }.

Tuple(&'hir [StructField<'hir>]HirId)

A tuple variant.

E.g., Bar(..) as in enum Foo { Bar(..) }.

Unit(HirId)

A unit variant.

E.g., Bar = .. as in enum Foo { Bar = .. }.

Implementations

Return the fields of this variant.

pub fn ctor_hir_id(&self) -> Option<HirId>[src]
