Most +ABI strings come in two variants, one with an `-unwind` suffix and one without. +The `Rust` ABI always permits unwinding, so there is no `Rust-unwind` ABI. If you expect Rust `panic`s or foreign (e.g. C++) exceptions to cross an FFI boundary, that boundary must use the appropriate `-unwind` ABI string.
