structslop analyzes Go structs to identify opportunities for size optimization. It analyzes the layout of struct fields and recommends reordering them to minimize memory allocation. The primary goal is to reduce the overall size of Go structs, leading to improved efficiency and potentially lower memory consumption. structslop leverages Go's internal size class system to determine optimal arrangements.
structslop provides detailed reports on struct sizes and potential optimizations, including percentage savings. It supports analyzing both Go packages and individual Go files. The tool is designed to be easily integrated into existing Go development workflows. It also offers a verbose mode for finer-grained analysis.
- Size Analysis: Reports on current struct size and potential savings with rearrangements.
- Go 1.20+ Compatibility: Designed for use with Go 1.20 and later versions.
- Flexible Input: Analyzes individual Go files or entire Go packages.
- Verbose Mode: Provides detailed information about size classes and potential optimizations.
- Command-Line Tool: Easily integrated into existing build and testing workflows.
- Testable: Includes test cases for verifying analyzer functionality.
- Efficiency Focused: Specifically targets reducing the memory footprint of Go structs.
structslop is an active project with recent commits and ongoing development. The documentation provides clear instructions for installation and usage, including running tests. While contribution guidelines are still under development, the project is actively maintained and appears reliable for basic struct size analysis.
Developers and performance engineers benefit from structslop by identifying and addressing inefficient struct layouts. This tool is useful in scenarios where memory footprint is a concern, such as high-performance applications or resource-constrained environments. It offers a valuable alternative to manual restructuring of structs, saving development time and improving application efficiency.
