pub struct TypeOptDomInnerV1 {
pub entries: Vec<TypeOptEntryV1>,
pub row_tail: Option<RowTailV1>,
}Expand description
A TypeOptDomV1’s group content: one or more label : typ entries
(nonempty enforced at lowering), then an optional | ?'r row-variable
tail (typ_opt_dom :756-757) — parsed, but rejected with a
LowerError (needs signature-level row quantification, not
implemented; contrast TypeRecordInnerV1’s own
row_tail, which IS fully supported, since a bare
record-typed value has no quant-list obligation to satisfy).

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>>(
