pub(crate) fn dots_kind(ty: &Type) -> Option<DotsKind>Expand description
The ... parameter type ty is, if any: Dots / &Dots
(DotsKind::Forced), or LazyDots taken by value (DotsKind::Lazy,
crate::type_inspect::is_lazy_dots_marker). &LazyDots and other
shapes are none; the callers refuse them by name.
