I want to print out a table in console of all the registered jobs, and I am having difficulties accessing those fields. This goes for a name particularly.

s.Every(5).Seconds().Name("somejob").Tag("sometag").Do(func() {
    fmt.Println("say something") 
}

for _, j := range s.Jobs() {
    fmt.Println(j)
}

This is the output I get:

&{0xc00001e198 {[246 117 117 190 84 191 68 235 148 179 141 122 35 140 157 133] 0xc0000a4280 {<nil> <nil> <nil> <nil> <nil> <nil>} 0x4c3f00 [] 0 somejob main.main.func1 {false 0 0} <nil> <nil> 0xc00001a1e8 0xc0000a41e0 0x49c980 0xc00001a1d0 0xc00001a1d8 0xc00001a1e0 <nil> <nil> 0xc00001a1f0 {0 0 <nil>}} 5 {<nil> false [0 0]} 0 1 true [] {0 0 <nil>} <nil> [] [] [sometag] <nil> <nil> false}</div>
