Go String after variable declaration

Question

Take a look at this snip found at here

import (
    \"encoding/xml\"
    \"fmt\"
    \"os\"
)

func main() {
    type Address struct {
        City, State string
             


        

Answer 1

It's a struct tag. Libraries use these to annotate struct fields with extra information; in this case, the module encoding/xml uses these struct tags to denote which tags correspond to the struct fields.
