Hi,

this is dpkg-buildpackage telling you that some build-dependencies are 
not met. Since all the alloy-* crates are under the crates/* directory 
in the root repository (assuming you based your package off of that), 
you need to drop the alloy* crates from debian/control and let cargo 
work its magic. A package that also uses internal crates is texlab or 
prs. You can look at them to see how things are built there. Feel free 
to reach out here or on the #debian-rust IRC channel in case you run 
into any more issues.

best,

werdahias
