From 3a87c697b2b860c9e48ff6ae7a40561af428f708 Mon Sep 17 00:00:00 2001 From: arookieofc <2128194521@qq.com> Date: Sun, 1 Nov 2026 17:48:38 +0800 Subject: [PATCH] fix(ide-tools): move run_input above the tests module (#677) clippy::items_after_test_module failed the workspace clippy run because run_input was defined after the first test module in crates/ide-tools/src/process.rs. Move it above; no code changes.
