Bug#1034032: rust-bitflags: autopkgtest regression: error[E0277]: the trait bound `SerdeFlags: Deserialize<'_>` is not satisfied

Thu, 06 Apr 2023 12:27:25 -0700 

Source: rust-bitflags
Version: 1.3.2-2
Severity: serious
Control: tags -1 bookworm-ignore
User: debian...@lists.debian.org
Usertags: regression

Dear maintainer(s),
Your package has an autopkgtest, great. However, it fails. Can you please investigate the situation and fix it? I copied some of the output at the bottom of this report.
The release team has announced [1] that failing autopkgtest on amd64 and arm64 are considered RC in testing. [Release Team member hat on] Because we're currently in the hard freeze for bookworm, I have marked this bug as bookworm-ignore. Targeted fixes are still welcome.
More information about this bug and the reason for filing it can be found on https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation 

Paul
