Hi!
Thanks for your report, it's always good to get fresh input from new users that
are not yet used to all the warts and rough edges.
I agree that dh-cargo should be made both more robust, and more generally
useful. As it stands, it's intended usecase is to package single crates using
a specific scheme, and packages deviating from that need to manually drive
the cargo wrapper (that dh-cargo also drives) instead of using dh-cargo, or
override lots of things.
The Rust Team book has some pointers for driving cargo directly:
https://rust-team.pages.debian.net/book/process-workspace.html#manual-wrapper-approach
I am not sure in which category your package falls, maybe it can use dh-cargo
with more hand-holding and overrides. I am happy to assist :)
I will try to include more relevant information and/or pointers in this
error message.
Regards,
Fabian
