| ?'r — a row-variable tail (shared by TypeOptDomInnerV1 and
TypeRecordInnerV1; parser_v1.mly:748-749/:756-757).

type Error = ParseError<<__SyanMacro_Atom as Spanned>::Span>
Every error must be convertible to the universal one, so a field’s failure can become the
enclosing type’s failure with no per-field where-predicate. Stating it HERE rather than at
each derived impl is what keeps it out of the obligation graph: a per-field
<FieldTy as Parse<Atom>>::Error: Into<…> predicate re-creates a projection cycle on a
recursive field (E0275), which decycle’s bound-peeling does not break.Source§fn parse_stream<__SyanMacro_S: ParseStream<Atom = __SyanMacro_Atom>>(
