}

Fields

tcx: TyCtxt<'tcx>

seen_fields: FxHashMap<Ident, FieldDeclSpan>

Implementations

impl<'tcx> FieldUniquenessCheckContext<'tcx>

fn new(tcx: TyCtxt<'tcx>) -> Self

fn check_field_decl(&mut self, ident: Ident, field_decl: FieldDeclSpan)

Check if a given field ident declared at field_decl has been declared elsewhere before.

fn check_field_in_nested_adt( &mut self, adt_def: AdtDef<'_>, unnamed_field_span: Span )

Check the uniqueness of fields across adt where there are nested fields imported from an unnamed field.

fn check_field(&mut self, field: &FieldDef<'_>)

Check the uniqueness of fields in a struct variant, and recursively check the nested fields if it is an unnamed field with type of an annoymous adt.

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.
