+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, some doctests 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 there entirely.
