[−][src]Enum syntax::ast::VariantData
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 = .. }
.
Methods

[src]
Return the fields of this variant.
pub fn ctor_id(&self) -> Option<NodeId>
[src]
