Functions

func EveryNil

func EveryNil(elems ...any) bool

EveryNil 检查所有元素是否都为 nil.

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.EveryNil())
	fmt.Println(base.EveryNil(nil))
	fmt.Println(base.EveryNil(nil, nil))
	fmt.Println(base.EveryNil(1))
	fmt.Println(base.EveryNil(1, nil))

}

Output:

true
true
true
false
false

func Result1

func Result1[R any](r R, _ ...any) R

Result1 返回第1个参数.

Example

package main

import (
	"fmt"
	"strconv"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.Result1(1, 2, 3, 4))
	fmt.Println(base.Result1(strconv.ParseInt("2", 10, 64)))

}

Output:

1
2

func Result2

func Result2[R any](_ any, r R, _ ...any) R

Result2 返回第2个参数.

Example

package main

import (
	"fmt"
	"os"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.Result2(1, 2, 3, 4))
	fmt.Println(os.IsNotExist(base.Result2(os.Stat("not exist"))))

}

Output:

2
true

func Result3

func Result3[R any](_, _ any, r R, _ ...any) R

Result3 返回第3个参数.

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.Result3(1, 2, 3, 4))

}

Output:

3

func Result4

func Result4[R any](_, _, _ any, r R, _ ...any) R

Result4 返回第4个参数.

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.Result4(1, 2, 3, 4))

}

Output:

4

func SomeNil

func SomeNil(elems ...any) bool

SomeNil 检查是否有元素为 nil.

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/base"
)

func main() {
	fmt.Println(base.SomeNil())
	fmt.Println(base.SomeNil(nil))
	fmt.Println(base.SomeNil(nil, nil))
	fmt.Println(base.SomeNil(1))
	fmt.Println(base.SomeNil(1, nil))

}

Output:

true
true
true
false
true
