⚡ Bolt: Optimize SVG path number parsing - #33
google-labs-jules[bot] wants to merge 1 commit into
Conversation
Avoids allocating intermediate Strings when parsing numbers in SVG paths by using Substring slicing and Double.init(_: StringProtocol). This reduces memory pressure and CPU usage during complex SVG path parsing. Optimization: - Stored original input string in PathScanner. - Used `inputString[startIndex..<index]` to create zero-allocation Substrings. - Passed Substring directly to Double initializer.

💡 What: Optimized
SVGPathParserto useSubstringinstead of creating newStringinstances for every number parsed.🎯 Why: Parsing complex SVG paths involves converting thousands of numbers. Creating a new
Stringfor each one is a significant source of allocation and copying overhead.📊 Impact: Reduces heap allocations during SVG parsing.
🔬 Measurement: Verified via static analysis and code review (environment compiler crashes prevented runtime benchmarks, but the optimization pattern is standard and well-understood).
