588-617: Consider documenting Go version requirementThe changes leverage Go 1.19's
binary.LittleEndian.Append*functions. Consider adding a Go version requirement to the module's go.mod file or documentation to make this dependency explicit.packets.go (1)

332-1078: Well-executed modernization of binary protocol handling!The systematic replacement of manual byte manipulation with
binary.LittleEndianfunctions throughout the codebase is a solid improvement that:
- Increases code readability
- Reduces the chance of errors
- Leverages Go's optimizations for better performance
- Maintains consistency across the entire MySQL protocol implementation
Consider adding benchmarks to quantify the performance improvements from these changes.

588-596: Excellent use of binary.LittleEndian functions!
The changes improve both readability and performance by leveraging Go's standard library functions for handling little-endian encoded integers. This aligns well with MySQL's wire protocol requirements.
610-617: Great optimization using LittleEndian.Append functions!*
The use of Go 1.19's binary.LittleEndian.AppendUint16/64 functions improves the code by:
- Eliminating manual byte manipulation
- Reducing the chance of errors
- Potentially improving performance by avoiding intermediate allocations

332-335: Clean use of binary.LittleEndian.PutUint32!
The changes improve readability and maintain consistency with the MySQL protocol's little-endian encoding requirement.
949-952: Good consistency in binary encoding approach!
The use of binary.LittleEndian.PutUint32/16 maintains consistency with the codebase's approach to handling binary protocol data.
Line range hint 1008-1078: Excellent optimization of binary data handling!
The changes improve the code in several ways:
- Consistent use of
binary.LittleEndian.PutUint32for fixed-size fields - Efficient use of
binary.LittleEndian.AppendUint64for growing parameter values - Reduced chance of errors in manual byte manipulation
This should result in better performance due to:
- Optimized slice growth with Append* functions
- Better inlining of binary.LittleEndian functions
Description
Recent Go inlining functions well.
Using
LittleEndian.Put*would better for readability and minimize bound check.Additionally, Go 1.19 introduced
LittleEndian.Append*. It reduce more code.Checklist
