Expand description

Fields and constructor IDs of enum variants and structs.

Variants

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

A struct variant.

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

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

A tuple variant.

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

Unit(HirId)

A unit variant.

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

Implementations
