Use `macro_rules` lifetime specifier when it lands in stable #246

Open gburd opened 4 years ago

gburd commented 4 years ago

This will enable the FFI to specialise define_destructor and use repetitions to allow more generic lifetime handling instead of having two functions.

Code is landed but awaiting release to stable. https://github.com/rust-lang/rust/issues/34303
