Performance Optimization and Memory Usage Reduction by Sorting Fields in Go Structs

By rearranging the fields in the struct from the first example to the second one, performance can be improved and memory usage reduced by sorting fields in Go structs.

type BadStruct struct {
    age          uint8
    IdCardNumber uint64
    DateOfBirth  uint16
}

type GoodStruct struct {
    age          uint8
    DateOfBirth  uint16
    IdCardNumber uint64
}
