Functions ¶
func IsNil ¶
IsNil returns true if the input value is nil.
Example ¶
package main
import (
"fmt"
"github.com/Vonage/gosrvlib/pkg/typeutil"
)
func main() {
var nilChan chan int
v := typeutil.IsNil(nilChan)
fmt.Println(v)
}
Output: true
func IsZero ¶
IsZero returns true if the input value is equal to the zero instance (e.g. empty string, 0 int, nil pointer).
Example ¶
package main
import (
"fmt"
"github.com/Vonage/gosrvlib/pkg/typeutil"
)
func main() {
var zeroInt int
v := typeutil.IsZero(zeroInt)
fmt.Println(v)
}
Output: true
func Pointer ¶ added in v1.75.1
func Pointer[T any](v T) *T
Pointer returns the address of v.
Example ¶
package main
import (
"fmt"
"github.com/Vonage/gosrvlib/pkg/typeutil"
)
func main() {
v := 5
p := typeutil.Pointer(v)
fmt.Println(p)
}
Output:
func Value ¶ added in v1.75.1
func Value[T any](p *T) T
Value returns the value of the provided pointer or the type default (zero value) if nil.
Example ¶
package main
import (
"fmt"
"github.com/Vonage/gosrvlib/pkg/typeutil"
)
func main() {
num := 5
p := &num
v := typeutil.Value(p)
fmt.Println(v)
}
Output: 5
