Go中的闭包

使用go build -gcflags -m ./func.go可以看到这样的信息 # command-line-arguments ./func.go:9: can inline func·001 ./func.go:9: func literal escapes to heap ./func.go:8: moved to heap: i ->显示会将闭包函数所引用的空间移到堆中。避免以后的闭包调用找不到目标。 ./func.go:10: &i escapes to heap ./func.go:11: func literal escapes to heap ./func.go:12: &i escapes to heap ./func.go:12: func·002 ... argument does not escape

比如： ```go var name = "abc" go func(){ fmt.Println(name) }() ```

保存到func.go ```go package main import ( "fmt" ) func Func() (func(), func()) { i := 10 return func() { i++ }, func() { fmt.Println(i) } } func main() { Add, Print := Func() for i := 0; i < 10; i++ { Add() } Print() } ``` 使用go build -gcflags -m ./func.go可以看到这样的信息 # command-line-arguments ./func.go:9: can inline func·001 ./func.go:9: func literal escapes to heap ./func.go:8: moved to heap: i ->显示会将闭包函数所引用的空间移到堆中。避免以后的闭包调用找不到目标。 ./func.go:10: &i escapes to heap ./func.go:11: func literal escapes to heap ./func.go:12: &i escapes to heap ./func.go:12: func·002 ... argument does not escape
