+
+缓存组件
+
+## API
+- Set 设置缓存,带失效时间
+- SetDefault 设置缓存,使用默认的缓存时间
+- SetNoExpire 设置缓存,不过期
+- SetIfAbsent 设置缓存,如果不存在设置成功返回bool
+- Replace 替换缓存,如果存在设置成功返回bool
+- Delete 删除缓存
+- Get 获取缓存,返回对应V以及bool
+- GetWithExpire 获取缓存,返回对应V以及bool以及过期时间
+- Count 获取缓存数量
+- Clear 清空缓存
+- Load 从文件加载对象
+- Export 导出到文件
+- Marshal 
+- Unmarshal
+
+## EXAMPLE
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/songzhibin97/go-baseutils/app/bcache"
+	"github.com/songzhibin97/go-baseutils/base/bcomparator"
+	"time"
+)
+
+func main() {
+	c := bcache.New[int, int](bcomparator.IntComparator())
+	c.Set(1, 1, 5*time.Second)
+	fmt.Println(c.Get(1)) // 1,true
+	time.Sleep(5 * time.Second)
+	fmt.Println(c.Get(1)) // 0,false
+}
+

+channel一些最佳实践
+
+## API
+- FanInRec 扇入模式
+- MergeChannel 合并channel
+- FanOut 扇出模式
+- MapChan 对channel中的元素进行map操作
+- ReduceChan 对channel中的元素进行reduce操作
+- OrDone 任意channel完成后返回
+- Orderly 顺序并发执行
+- Pipeline 串联执行
+- Stream 流式操作
+- TaskN 只取流中的前N个数据
+- TaskFn 筛选流中的数据,只保留满足条件的数据
+- TaskWhile 只取满足条件的数据,一旦不满足就不再取
+- SkipN 跳过流中的前N个数据
+- SkipFn 跳过满足条件的数据
+- SkipWhile 跳过满足条件的数据,一旦不满足,当前这个元素以后的元素都会输出
