+Subject: [PATCH] EPEL9: Ignore doctests that require very recent Rust
+ compilers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In this crate, doctests and examples (but not the lib and integration tests) are allowed to use Rust features from versions newer than the MSRV. It’s therefore necessary to ignore some of them on EPEL9. If this patch becomes too unwieldy, we could choose to start skipping doctests and/or examples there entirely.
