Enum rustc_ast::ast::VariantData
source · Expand description
Fields and constructor ids of enum variants and structs.
Variants
Struct(Vec<FieldDef>, bool)
Struct variant.
E.g., Bar { .. }
as in enum Foo { Bar { .. } }
.
Tuple(Vec<FieldDef>, NodeId)
Tuple variant.
E.g., Bar(..)
as in enum Foo { Bar(..) }
.
Unit(NodeId)
Unit variant.
E.g., Bar = ..
as in enum Foo { Bar = .. }
.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
