Functions ¶
func CompareIntSlice ¶
CompareIntSlice 比较两个int型切片是否相等， true：相等， false：不相等
func GenerateUUID ¶
func GenerateUUID() string
func If ¶
func If[K comparable](cond bool, Then K, Else K) K
func InitLocalCache ¶
func InitLocalCache(maxSizeMB int)
func Int64ToDateString ¶
func Int64ToTimeString ¶
func InterfaceToDuration ¶
func InterfaceToInt64 ¶
func InterfaceToInt64(data interface{}) int64
func InterfaceToString ¶
func InterfaceToString(data interface{}) string
func IsRecordNotFoundError ¶
func IsSliceInt ¶
func ReadBigFile ¶
ReadBigFile 大文件读取 适合：常规带换行符，单行没有超过4069个字节的
func ReadBinaryFile ¶
ReadBinaryFile 大文件读取 适合：读取二进制文件，如音频视频流
func RemoveReplicaSliceString ¶
* * slice(string类型)元素去重
func StructSort ¶
按照字段排序，需要注意是否有该字段和字段类型
Types ¶
type Bucket ¶
type Bucket struct {
Slice []interface{} //承载以任意结构体为元素构成的Slice
By func(p, q *interface{}) bool //排序规则函数,当需要对新的结构体slice进行排序时，只需定义这个函数即可
}
通用结构体排序 结构体排序，必须重写数组Len() Swap() Less()函数
type LocalCache ¶
type LocalCache struct {
CacheSize int
// contains filtered or unexported fields
}
LocalCache 使用了freecache、支持缓存淘汰、线程安全
var LocalCacheInstance LocalCache
func (*LocalCache) Del ¶
func (l *LocalCache) Del(key string)
func (*LocalCache) Get ¶
func (l *LocalCache) Get(key string) string
func (*LocalCache) Set ¶
func (l *LocalCache) Set(key, value string, expire int)
type Set ¶
type Set[K comparable] struct { // contains filtered or unexported fields }
Set 不支持并发操作的Set
func NewSet ¶
func NewSet[K comparable](items ...K) *Set[K]
type UUID ¶
type UUID [16]byte
A UUID is a 128 bit (16 byte) Universal Unique IDentifier as defined in RFC 4122.
func NewRandom ¶
NewRandom returns a Random (Version 4) UUID.
The strength of the UUIDs is based on the strength of the crypto/rand package.
Uses the randomness pool if it was enabled with EnableRandPool.
A note about uniqueness derived from the UUID Wikipedia entry:
Randomly generated UUIDs have 122 random bits. One's annual risk of being hit by a meteorite is estimated to be one chance in 17 billion, that means the probability is about 0.00000000006 (6 × 10−11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate.
func (UUID) String ¶
String returns the string form of uuid, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx , or "" if uuid is invalid.
func (UUID) URN ¶
URN returns the RFC 2141 URN form of uuid, urn:uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, or "" if uuid is invalid.
