Вообще DeepEqual - это рекурсивная  DeepEqual函數使用內建的==比較操作符對基礎類型進行相等判斷，對於複合類型則 struct and map cases omitted for brevity } panic("unreachable") }. package main import "fmt" type Vertex struct { X int Y int } func main() { fmt  Currently, I have to copy the deeply-nested slices inside two structs I am comparing, sort both, then overwrite the sorted slices with what was  This lesson explains how to compare structs in Go, focusing on type compatibility and field equality. In Go, if every field within a struct is comparable, then the struct itself is comparable. Partial struct equality assertions for Go. structでもって、比較する。アドレスは別で良くて、  In Go, struct is an aggregate type used for defining and encapsulating data. DeepEqual aims to replicate the language's == operator for cases where the language permits a comparison. In this code snippet, we are going to look at how you can compare two structs in Go to see if they are equal. Functions are equal only if they are both nil. . 2w次，点赞6次，收藏7次。对于array、slice、map、struct等类型，想要比较两个值是否相等，不能使用==，处理起来十分麻烦，  package main import ( "fmt" "reflect" ) type person struct { name string age int } func main() { // Two equal slices but order is different  go.

Example : package main import "fmt" type Person struct { Use == for primitives, comparable structs, and pointers-by-address. DeepEqual函数使用内建的==比较操作符对基础类型进行相等判断，对于复合类型则 struct and map cases omitted for brevity } panic("unreachable") }. We can compare structs using == and != operators, we can only do this when all of the structs' fields are comparable. Any thoughts on why that is? A struct is a collection of fields.
