Functions ¶
func DeduplicationFunc ¶
func DeduplicationFunc[T comparable](vs []T, fn func(T) string) []T
DeduplicationFunc 自定义条件去重
func NextTimeTomorrow ¶ added in v1.2.9
NextTimeTomorrow 计算距离明天指定时间还有多久 hour: 0-23, minute: 0-59, second: 0-59 返回距离明天指定时间的时长
func NextTimeWithFirst ¶ added in v1.2.9
NextTimeWithFirst 创建一个闭包函数，第一次调用返回 firstWait，之后调用返回 fn() 的结果
func UseMemoryUsage ¶ added in v1.2.3
func UseMemoryUsage() func() uint64
UseMemoryUsage 计算内存占用 cost := UseMemoryUsage() defer cost()
func UseTiming ¶
UseTiming 计算函数花销，超过 limit 用 error 级别记录 cost := UseTiming(time.Second) defer cost() 业务操作
func UseTimingWithLog ¶ added in v1.2.5
UseTimingWithLog 计算函数花销，超过 limit 用 error 级别记录
Types ¶
type CacheFn ¶
type CacheFn[K comparable, V any] func(K) (V, bool, error)
CacheFn 缓存函数
func UseCache ¶
func UseCache[K comparable, V any](fn func(K) (V, error)) CacheFn[K, V]
UseCache 使用内存缓存一些临时数据 由于是临时数据，其 value 应该是一次性数据，用完即丢 第二个返回参数用来标识是否命中缓存
func UseTTLCache ¶
UseTTLCache 使用内存缓存一些临时数据 指定时间超时自动清理
