Enum rustc_ap_rustc_ast::ast::VariantData

pub enum VariantData {
    Struct(Vec<StructField>, bool),
    Tuple(Vec<StructField>, NodeId),
    Unit(NodeId),
}

Fields and constructor ids of enum variants and structs.

Variants

Struct(Vec<StructField>, bool)

Struct variant.

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

Tuple(Vec<StructField>, NodeId)

Tuple variant.

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

Unit(NodeId)

Unit variant.

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