This Rust crate is a dependency for Waypipe's rewritten Rust version [1]. It has several workspace members, but I believe only the "ash" member from the workspace is needed (if something depends on a crate named "foo", which is a workspace member in a crate called "foo", then it's the workspace-member foo that is the actual dependency, right?). That workspace member builds fine on Debian sid. However: ash is a *generated* crate. The checked-in sources are generated from Vulkan headers, and then published as the ash crate (yuck!). That seems counter to Debian policy. The generator [2], in turn, has dependencies not yet in Debian. I am therefore hoping to solicit help and/or advice from the Rust team on packaging ash.

Hi Gard,this is indeed unfortunate :( I maintain the GTK-rs binding who suffer from a similar issue. They are generated from the .gir instrospection data of the relevant libraries. This caused issues with ftpmasters, and I opted to regenerate all source code before build. This is annoying because it causes ever so sligthly code diff. Most of the time it's fine though. I fear you would need to do the same procedure here wrt the vulkan headers. This means: Packaging the generator, and then re-generating the rust code against our vulkan headers. I can't promise that this won't cause its own issues. Maybe reach out to upstream about this (that they align the vulkan headers to what we have )? src:rust-gtk4 gives you an idea how the code regeneration works with GTK (see d/rules). Let me know if you need any help with packaging the generator and regenerating code.
best, werdahias
