It needs to be analyzed in detail , If struct Contains field types that cannot be compared , Can't be compared , If struct All field types in support of comparison , Then it can be compared .

A type that cannot be compared : ① slice, because slice Is a reference type , Unless it's with nil Compare ② map, and slice Empathy , If you want to compare two map Can only be achieved by loop traversal ③ Function type

Other types can be compared .

There are two other points to note ：

• Structures can only compare whether they are equal , Instead of comparing their sizes .
• Only structures with equal attributes and consistent attribute order can be compared .
