+name: PR Test (Rust extensions)
+
+# In-crate checks for the Rust extensions bundled with the `sglang` wheel
+# (rust/sglang-mm). The pyo3 bindings themselves are exercised by the Python
+# unit suite (base-a-test-cpu), which builds the extensions from source; this
+# job covers the pure-Rust core, exactly as sglang-server links it, plus lints.
+#
+# Scoped to sglang-mm on purpose: sglang-server and sglang-grpc have no
+# in-crate test suite yet, so a `rust/**` trigger would spawn a job that does
+# not actually cover the changed crate. Widen the paths together with the job.
