From afdc46f436b0efabab9015db6c463cbefc7aeec6 Mon Sep 17 00:00:00 2001 From: whitelonng Date: Sun, 21 Jun 2026 20:23:20 +0800 Subject: [PATCH] refactor: apply cargo clippy fixes to improve code quality MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Applied clippy suggestions to improve code quality and maintainability, reducing warnings from 27 to 2. Changes: - Remove unused import: Manager from lib.rs - Replace sort_by with sort_by_key using Reverse for cleaner sorting - mobile_server.rs: session list sorting - agent/sessions.rs: session list sorting - Replace manual loop counter with enumerate() in llm/mod.rs - Collapse nested if let into single pattern match in book_travel.rs - Apply 20 automatic clippy fixes for: - Redundant return statements - Collapsible if statements - Iterator optimizations (replace .last() on DoubleEndedIterator) - Unnecessary borrows - Manual implementations of standard methods - Other idiomatic Rust patterns Remaining warnings (2): Two "too many arguments" warnings remain for functions that would require larger refactoring to use parameter structs: - call_background_llm (11 params) in agent/sessions.rs - emit_tool_event (9 params) in agent/mod.rs These are candidates for future refactoring but are deferred to avoid large changes affecting multiple call sites.
