BackupAndWrite creates a backup and writes to a file

func CalculatePadding

func CalculatePadding(fields []optimizer.FieldInfo) int64

CalculatePadding computes the total padding size

func CompareFields

func CompareFields(orig, new []string) bool

CompareFields compares two field lists

func CreateFieldInfo

func CreateFieldInfo(name string, size, align int64, isEmbed bool, typeName string) optimizer.FieldInfo

CreateFieldInfo creates a field info entry (for testing)

func FieldsChanged

func FieldsChanged(orig, new []optimizer.FieldInfo) bool

FieldsChanged checks whether fields have changed

func GenerateStructCode

func GenerateStructCode(name string, fields []optimizer.FieldInfo) string

GenerateStructCode generates struct source code

func GetStructFields

func GetStructFields(filePath, structName string) ([]string, error)

GetStructFields returns the field list of a struct (for debugging)

func GroupFieldsBySize

func GroupFieldsBySize(fields []optimizer.FieldInfo) map[int64][]optimizer.FieldInfo

GroupFieldsBySize groups fields by their size
