From 0a93123859f006b8df21a60809f4ac4c95e242aa Mon Sep 17 00:00:00 2001 From: Bradley Nelson Date: Mon, 22 Jun 2026 10:37:57 -0600 Subject: [PATCH] style(bench): rustfmt the blob/pool/runtime bench examples These example targets landed unformatted on main and fail the Rustfmt CI check (`cargo fmt --all --check`); reformat them so this PR's checks pass.
