Type Definition rustc_builtin_macros::deriving::generic::EnumNonMatchCollapsedFunc

pub type EnumNonMatchCollapsedFunc<'a> = Box<dyn FnMut(&mut ExtCtxt<'_>, Span, &[Ident]) -> P<Expr> + 'a>;

Deal with non-matching enum variants. The slice is the identifiers holding the variant index value for each of the Self arguments.

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.
