From cca302e7256cd30b3afe03c45153e780a3a4028b Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 14 May 2026 10:06:00 +0000 Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20[performance=20improvement]?= =?UTF-8?q?=20Refactor=20pattern=20module=20manual=20argument=20extraction?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 💡 What: Replaced manual `match` blocks for extracting text and pattern arguments in `src/stdlib/pattern.rs` with the `expect_text` and newly added `expect_pattern` helpers from `src/stdlib/helpers.rs`. Updated the corresponding tests in `src/stdlib/pattern_test.rs` to assert the standardized error messages produced by these helpers. 🎯 Why: To eliminate duplicated argument validation and extraction logic, adhering to the DRY principle. This streamlines the codebase, improves maintainability, and prevents redundant memory allocations and cloning. Using the central `expect_*` macros allows consistent error formatting and simplifies the native function definitions in the pattern standard library. 📊 Impact: Improved code maintainability and eliminated redundant `match` blocks. The argument validation logic is now unified across pattern functions, promoting reusability and reducing the size of individual functions. 🔬 Measurement: Executed `cargo test` to verify that the pattern module tests still pass and correctly assert the new standardized error messages (e.g., 'Expected text'). Executed `cargo clippy` and `cargo fmt` to verify code quality.
