I am trying to create a pseudo queue structure and insert jobs structs inside it. What am I doing wrong ?
import "fmt"
type Job struct {
Type string
Url string
}
type Queue [] Job
func main() {
var queue []Queue
job := Job{"test", "http://google.com"}
queue[0] = job
fmt.Println(queue)
}
The code above is throwing:
cannot use job (type Job) as type Queue in assignment
I think problem is here:
var queue []Queue
Here queue is a slice of Queue or slice of slice of Job. So it's impossible to assign first its element value of Job.
Try:
var queue Queue
queue was just created and has no zeroth element. Using append add such element. Have you checked len and cap functions for slice?You don't need a slice of queues, and you should not index an empty slice.
package main
import "fmt"
type Job struct {
Type string
Url string
}
type Queue []Job
func main() {
var q Queue
job := Job{"test", "http://google.com"}
q = append(q, job)
fmt.Println(q)
}
[]TypeName is definition of slice of TypeName type.
Just as it said:
var queue []Queue is a slice of instances of type Queue.
q := Queue{Job{"test", "http://google.com"}, Job{"test", "http://google.com"}}
Definitely it is not what you want. Instead of it you should declare var queue Queue:
var queue Queue
q := append(queue, Job{"test", "http://google.com"}, Job{"test", "http://google.com"})
[]invar queue []Queue, you'll still get runtime error though.
