Enum syntax::ast::VariantData [] [src]

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

Fields and Ids of enum variants and structs

For enum variants: NodeId represents both an Id of the variant itself (relevant for all variant kinds) and an Id of the variant's constructor (not relevant for Struct-variants). One shared Id can be successfully used for these two purposes. Id of the whole enum lives in Item.

For structs: NodeId represents an Id of the structure's constructor, so it is not actually used for Struct-structs (but still presents). Structures don't have an analogue of "Id of the variant itself" from enum variants. Id of the whole struct lives in Item.

Variants

Struct variant.

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

Tuple variant.

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

Unit variant.

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