[Pkg-rust-maintainers] Bug#947710: rust-fallible-iterator: autopkgtest failure

[Paul Gevers]

Source: rust-fallible-iterator
Version: 0.2.0-1
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainers,

With a recent upload of rust-fallible-iterator you added an autopkgtest
to your package, great. However, it fails. I copied some of the output
at the bottom of this report. It seems to me that this package is not
the only package in the rust ecosystem that is failing its new
autopktest, so probably there is something to fix in the generating
code. I am not familiar with the rust ecosystem, hence I'm filing
against the failing package.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

More information about this bug and the reason for filing it can be found on
