chrono crate 的 Json 序列化功能 [英] Json Serialization feature of chrono crate

问题描述

我正在尝试将 rust-chrono 板条箱中的 DateTime 用于我自己的特征.

I'm trying to use DateTime from rust-chrono crate to my own trait.

#[derive(Debug, RustcEncodable, RustcDecodable)]
pub struct Accomplishment {
  name: String,
  accomplishment_type: String,
  date: DateTime<UTC>
}

当我尝试编译它时它抱怨

When I try to compile this it complains that

src/lib.rs:11:33: 11:47 error: the trait `rustc_serialize::serialize::Decodable` is not implemented for the type `chrono::datetime::DateTime<chrono::offset::utc::UTC>` [E0277]
src/lib.rs:11 #[derive(Debug, RustcEncodable, RustcDecodable)]

当我检查 github repo of chrono 时，它实现了 rustc_serialize 支持.但它是一个功能.在 提交日志中有

When I checked the github repo of chrono it had the rustc_serialize support implemented. But it is as a feature. In commit log it has

cargo test -v --features rustc-serialize

我不确定如何为我的项目提供此功能.有人可以帮助我如何在 rustc-serialize 中使用 chrono 吗?

I'm not sure how to have this feature for my project. Can someone help me on how to use chrono with rustc-serialize?

有一个关于此的类似问题.但我想要的是在我的项目中使用 chrono 中可用的序列化支持，而无需实现包装器特征.

There is a similar question regarding this. But what I wanted is to use the serialization support available in chrono in my project without implementing a wrapper trait.

推荐答案

在 Cargo.toml

[dependencies.chrono]
version = "*"
features = ["rustc-serialize"]
