Functions

func IsNil

func IsNil(i any) bool

IsNil checks that the interface contains a nil value.

Example

type Obj struct{}

var obj *Obj
var a any = obj
fmt.Println(IsNil(a))

obj = &Obj{}
a = obj
fmt.Println(IsNil(a))

Output:

true
false

func IsType

func IsType[T any](v any) bool

IsType checks type.

Example

type Obj1 struct{}
type Obj2 struct{}

fmt.Println(IsType[Obj1](Obj1{}))
fmt.Println(IsType[Obj2](Obj1{}))

Output:

true
false

func SameType

func SameType(v1, v2 any) bool

SameType checks that values has the same type. It uses the reflection.

Example

type Obj1 struct{}
type Obj2 struct{}

fmt.Println(SameType(Obj1{}, Obj1{}))
fmt.Println(SameType(Obj1{}, Obj2{}))

Output:

true
false
