Update needed for Rust v1.77.1

error: field `0` is never read

   | in this macro invocation
   |
   = note: `BitTube` has a derived impl for the trait `Debug`, but this is intentionally ignored during dead code analysis
   = note: `-D dead-code` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(dead_code)]`
   = note: this error originates in the macro `stub_unstructured_parcelable` (in Nightly builds, run with -Z macro-backtrace for more info)
help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field
