Expand description
Fields and constructor ids of enum variants and structs.
Variants§
Struct(ThinVec<FieldDef>, bool)
Struct variant.
E.g., Bar { .. }
as in enum Foo { Bar { .. } }
.
Tuple(ThinVec<FieldDef>, NodeId)
Tuple variant.
E.g., Bar(..)
as in enum Foo { Bar(..) }
.
Unit(NodeId)
Unit variant.
E.g., Bar = ..
as in enum Foo { Bar = .. }
.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
