Empty slice literal of type "[]SSHKeyPair" used to define "labels"

46func (keypair *SSHKeyPair) QuerySSHKeyPairLabels() ([]SSHKeyPair, error) {
47 db := connect()
48 labels := []SSHKeyPair{} 49 rows, err := db.Query("SELECT id, label from sshpair")
50 if err == sql.ErrNoRows {
51 ErrNoRows = sql.ErrNoRows
Description
An empty slice can be represented by nil or an empty slice literal. They are
functionally equivalent — their len and cap are both zero — but the nil
slice is the preferred style. For more information about empty slices,
see Declaring Empty Slices.
Bad practice
package main
func foo() {
a := []int{}
}
Recommended
package main
func foo() {
var a []int
}
