# The io_uring CI lane runs `cargo test -p rustfs-ecstore --lib uring_`.
#
# `--lib` is there to avoid compiling and linking the 7 integration binaries
# under crates/ecstore/tests/, which selected zero tests for this filter. That is
# only safe while it stays true: add a matching test under tests/ and `--lib`
# would skip it silently, with CI staying green — the failure mode is invisible,
# so it is asserted here instead.
#
# The pattern must use the same `uring_` substring semantics as libtest, which
# also matches names containing `during_`. Narrowing it to `io_uring` would make
# this guard disagree with the filter it is protecting.
#
# Usage: scripts/check_uring_lane_lib_only.sh
