[lancet](https://github.com/duke-git/lancet) 是一个全面、高效、可复用的go语言工具函数库。 本次发布v2.0.0版本，全面升级go1.18，应用泛型重写大部分函数。同时新增70+函数。
## 特性
- 全面、高效、可复用
- 250+常用go工具函数，支持string、slice、datetime、net、crypt...
- 只依赖go标准库
- 所有导出函数单元测试覆盖率100%
## 安装
### Note:
- <b>对于使用go1.18及以上的用户，建议安装v2.x.x。 因为v2.x.x用go1.18的泛型重写了大部分函数。</b>
```go
go get github.com/duke-git/lancet/v2 //安装v2最新版本v2.x.x
```
- <b>使用go1.18以下版本的用户，必须安装v1.x.x。目前最新的v1版本是v1.2.6。</b>
```go
go get github.com/duke-git/lancet@v1.2.6 // 使用go1.18以下版本, 必须安装v1.x.x版本
```
## 用法
lancet是以包的结构组织代码的，使用时需要导入相应的包名。例如：如果使用字符串相关函数，需要导入strutil包:
```go
import "github.com/duke-git/lancet/v2/strutil"
```
## 例子
此处以字符串工具函数ReverseStr（逆序字符串）为例，需要导入strutil包:
```go
package main
import (
"fmt"
"github.com/duke-git/lancet/v2/strutil"
)
func main() {
s := "hello"
rs := strutil.ReverseStr(s)
fmt.Println(rs) //olleh
}
```
