Variants

Struct(&'hir [FieldDef<'hir>], bool)
Expand description

A struct variant.

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

Tuple(&'hir [FieldDef<'hir>], HirId)
Expand description

A tuple variant.

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

Unit(HirId)
Expand description

A unit variant.

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