英文:
What are filtered field tags in Golang structs?
问题
type User struct {
Id int
Password string filtered:"true"
}
关于filtered:"true"部分的说明。我从未在其他地方见过这个，也找不到规范中的任何相关信息。可能类似于不导出字段吗？
有人有更多信息吗？
英文:
type User struct {
Id int
Password string `filtered:"true"`
}
Referring to the filtered: "true" part. Never seen this anywhere else, and can't find anything in the spec about it. Presumably it's similar to not exporting a field?
Does anyone have more information?

在语言中，结构标签没有被赋予特殊的含义，它们是由查找它们的包进行解释的。
在这种情况下，filtered:true 对使用 User 类型的包来说有特定的含义，并根据自己的需要进行处理。这与 encoding/json 中的 json: 标签的工作方式相同。
英文:
There is no special meaning assigned to struct tags by the language, they are interpreted by the package looking for them.
In this case, filtered:true means something to the package that uses the User type, and acts on that however it sees fit. This is the same as how the json: tags work in encoding/json.
