如何在表单中使用 Rocket_contrib::Uuid？

如何解决如何在表单中使用 Rocket_contrib::Uuid？

我使用的是 0.5.0-dev 版本的 Rocket 和 Rocket_contrib。我想在表单中使用 Uuid，但出现以下编译错误：

特性 `FromFormField` 没有为 `rocket_contrib::uuid::Uuid` 实现

根据 docs Uuid 实现 FromFormField，我不明白这一点。我做错了什么？

#[macro_use]
extern crate rocket;

use rocket::data::TempFile;
use rocket::form::{datafield,Form};
use rocket_contrib::uuid::Uuid;

#[derive(FromForm)]
struct FileUploadForm<'v> {
    id: Uuid,file: TempFile<'v>,}

#[post("/upload",data = "<data>")]
fn upload(data: Form<FileUploadForm>) -> Result<String,std::io::Error> {
    let id = "uuid".to_string();
    Ok(id)
}

fn rocket() -> rocket::Rocket {
    rocket::ignite().mount("/",routes![upload])
}

#[rocket::main]
async fn main() {
    rocket().launch().await;
}

解决方法

我的 Cargo.toml 不正确，我没有正确包含 rocket_contrib。正确的版本如下

[package]
name = "stackoverflow"
version = "0.1.0"
edition = "2018"

[dependencies]
rocket = { git = "https://github.com/SergioBenitez/Rocket",version = "0.5.0-dev" }

[dependencies.rocket_contrib]
git = "https://github.com/SergioBenitez/Rocket"
version = "0.5.0-dev"
default-features = false
features = ["uuid"]
