编译器错误将切片附加到切片

Question

The Go compiler is complaining about my code to append a slice to a slice. Here are relevant excerpts:

type LanidEntry struct {
    lanid   string
    group   string
    contact string
}

var lanids []LanidEntry

func load_file() (lanids_loaded []LanidEntry, errormsgs string) {
    // ...
}

func Load() (lanids []LanidEntry, errormessages string) {
    lanids_loaded, errormsgs := load_file(filename1, contact1)
    lanids = append(lanids, lanids_loaded)
    // ...
}

The append line generates this compiler message:

 src\load_lanids\load_lanids.go:50: cannot use lanids_loaded (type []LanidEntry) as type LanidEntry in append

I know that appending slices to slices works fine, based on an example in a Go Blog post under the section headed Append: The built-in function.

Answer 1

You need to use ...:

lanids = append(lanids, lanids_loaded...)

Also, also please format your code :)
