[Pkg-rust-maintainers] Bug#1056639: FTBFS: requires network during mandatory build steps

[Sven Mueller]

Package: rust-urlshortener
Version: 3.0.2-1
Severity: grave

Justification for severity: Policy violation

During a rebuild of Debian testing, we ran into this test failing during an
sbuild controlled build on a VM with limit network connectivity (only
configured APT repositories usable). See log excerpt below.

This network access is a violation of policy section 4.9:

For packages in the main archive, required targets must not attempt network
access, except, via loopback interface, to services on the build host that
have been started by the build.

Inspection of the source reveals that this test indeed tries to reach
targets in the internet.
