# Field
|
||||
|
||||
Field 包封装了一个抽象的`Field`结构体,提供了操作`struct`属性的相关函数
|
||||
|
||||
<div STYLE="page-break-after: always;"></div>
|
||||
|
||||
## 源码:
|
||||
|
||||
- [https://github.com/duke-git/lancet/blob/main/structs/field.go](https://github.com/duke-git/lancet/blob/main/structs/field.go)
|
||||
|
||||
<div STYLE="page-break-after: always;"></div>
|
||||
|
||||
## 用法:
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/duke-git/lancet/v2/structs"
|
||||
)
|
||||
```
|
||||
|
||||
<div STYLE="page-break-after: always;"></div>
|
||||
|
||||
## 目录:
|
||||
- [Tag](#Tag)
|
||||
- [Name](#Name)
|
||||
- [Value](#Value)
|
||||
- [Kind](#Kind)
|
||||
- [IsEmbedded](#IsEmbedded)
|
||||
- [IsExported](#IsExported)
|
||||
- [IsZero](#IsZero)
|
||||
- [IsSlice](#IsSlice)
|
||||
|
||||
> 注意:由于`Field`继承于`Struct`,所以同样拥有`Struct`所有方法,如下:
|
||||
|
||||
- [ToMap](https://github.com/duke-git/lancet/blob/main/docs/structs/struct_zh-CN.md#ToMap)
|
||||
- [Fields](https://github.com/duke-git/lancet/blob/main/docs/structs/struct_zh-CN.md#Fields)
|
||||
- [Field](https://github.com/duke-git/lancet/blob/main/docs/structs/struct_zh-CN.md#Field)
|
