Functions

func InGithubCI

func InGithubCI() bool

InGithubCI check github acitons envrionment https://help.github.com/en/actions/configuring-and-managing-workflows/using-environment-variables

func PanicFn

func PanicFn(fn func() error)

PanicFn panic if err is not nil

func RedisMarshal

func RedisMarshal(b any) ([]byte, error)

RedisMarshal use gob encode

Example

package main

import (
	"fmt"

	"github.com/datewu/gtea/utils"
)

type anCache []string

// MarshalBinary implements the encoding.BinaryMarshaler interface.
func (l anCache) MarshalBinary() ([]byte, error) {
	type a anCache
	a1 := a(l)
	return utils.RedisMarshal(a1)
}

// UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.
func (l *anCache) UnmarshalBinary(data []byte) error {
	type a anCache
	a1 := (*a)(l)
	return utils.RedisUnMarshal(data, a1)
}

func main() {
	data := anCache{"hello", "world"}
	bs, err := data.MarshalBinary()
	// before go1.21.0
	// [15 255 129 2 1 1 1 97 1 255 130 0 1 12 0 0 16 255 130 0 2 5 104 101 108 108 111 5 119 111 114 108 100]
	if err != nil {
		panic(err)
	}
	fmt.Println(bs)

}

Output:

[14 127 2 1 1 1 97 1 255 128 0 1 12 0 0 16 255 128 0 2 5 104 101 108 108 111 5 119 111 114 108 100]
