Returning a struct in Golang

I'm just starting with Golang and I am very confused about interacting with other packages and using structs. Right now I am simply trying to return the a struct generated by a method in the gopsutil library. Specifically the return of the following function: enter link description here

My code for this is the following:

package main

import (
    "fmt"

    "github.com/shirou/gopsutil/cpu"

)

func main() {

    cpu_times = getCpuTime()
    fmt.Println(cpu_times)

}

func getCpuTime() TimesStat {
    ct, _ := cpu.Times(false)

    return ct
}

This returns TimesStat as undefined. I tried returning a few different syntactical variations, however the only return value I have found that compiles is interface{}, which gets me the struct inside of brackets (eg [{values...}]) and that led to some other problems. I can't seem to find any examples of what I am trying to do. Any help appreciated thanks.

you need to include the package name before the type, like so:

func getCpuTime() []cpu.TimesStat { // with package name before type
    ct, _ := cpu.Times(false)

    return ct
}

since that is a slice of cpu.TimesStat, you probably want to add an index in the calling function or change the function to just return a single cpu.TimesStat. (thanks to @algrebre)
