问题描述

我有一个如下所示的JSON结构:

I have a JSON structure that looks like this:

{ "type": "suite", "event": "started", "test_count": 1 }

我想反序列化为这些结构:

I want to deserialize into these structs:

#[derive(Debug, Deserialize)]
enum ResultType {
    Suite,
    Test,
}

#[derive(Debug, Deserialize)]
enum ResultEvent {
    Started,
    Failed,
    Ok,
}

#[derive(Debug, Deserialize)]
struct JsonResult {
    #[serde(rename(deserialize = "type"))]
    test_type: ResultType,
    event: ResultEvent,
    test_count: Option<u32>,
}

我找不到使serde_json使用正确大小写的方法.我不断收到这些错误:

I can't find a way to make serde_json use the correct case. I keep getting these errors:

Error("unknown variant `suite`, expected `Suite` or `Test`", line: 1, column: 17)

如果我将枚举值的大小写更改为全部小写或全部大写,则可以,但是我希望能够使用PascalCase.

If I change the case of the enum values to all lowercase or all uppercase it works, but I'd like to be able to use PascalCase.

推荐答案

您只需将 c1> 在枚举定义之前.

You just need to put #[serde(rename_all = "snake_case")] before the enum definition.
