Functions

func Bytes2String

func Bytes2String(b []byte) string

func FormatDateTime

func FormatDateTime(s string) (time.Time, error)

func If

func If[T any](condition bool, trueVal, falseVal T) T

伪三元表达式 PS: 请注意，由于go的机制, trueVal, falseVal 都是已定值(在传入if前就确定了), 可能会导致panic

func JsonConv

func JsonConv(src any, dst any) error

func MapConv

func MapConv(src map[string]any, dst any) error

func NewTimeCache

func NewTimeCache[T any](expire time.Duration, getter func() (T, error)) *timeCache[T]

func Recover

func Recover(msg string, goAfterRecover func(err error))

Recover 恢复panic 仅限于在 go routine 中，放置在第一行执行 严禁在主线程使用

func SplitBy

func SplitBy(content, spliter, escape string) (ret []string)

使用分隔符与转义符对字符串进行分割 $content 字符串内容 $spliter 分隔符 $escape 转义符

func SplitHead

func SplitHead(content, spliter, escape string) (ret [2]string)

使用分隔符与转义符对字符串进行分割(只拆分出第一个) $content 字符串内容 $spliter 分隔符 $escape 转义符

func String2Bytes

func String2Bytes(s string) []byte

func ToTimeHookFunc

func ToTimeHookFunc() mapstructure.DecodeHookFunc

func Try

func Try(invoke func())

Try 保护方法运行

func TryCatch

func TryCatch(invoke func(), fallback func(err error))

TryCatch 保护方法运行，如果失败，则执行fallback方法

Types

type NoCopy

type NoCopy struct{}

func (*NoCopy) Lock

func (*NoCopy) Lock()

func (*NoCopy) Unlock

func (*NoCopy) Unlock()

type TimeCache

type TimeCache[T any] interface {
	Get() (T, error)
	Reset()
}
