Struct `Repr`

#[repr(transparent)]
pub(in ::io::error) struct Repr(pub(in ::io::error::repr) NonNull<()>, pub(in ::io::error::repr) PhantomData<ErrorData<CustomOwner>>);

The internal representation.

See the module docs for more, this is just a way to hack in a check that we indeed are not unwind-safe.

fn is_unwind_safe<T: core::panic::UnwindSafe>() {}
is_unwind_safe::<std::io::Error>();

Fields

0: NonNull<()>
