处理RuustDIESEL中的Jsonb PostgreSQL列

我有一张有Jsonb专栏的表格

diesel::table! {
    user (id) {
        id -> Uuid,
        data -> Jsonb,
        ...
    }
}

我创建了一个类似于这样的 struct :

use crate::schema::user;
use diesel::prelude::*;
use serde::{Deserialize, Serialize};
use uuid::Uuid;

#[derive(Serialize, Deserialize, Queryable, Insertable)]
#[table_name = "user"]
pub struct User {
    pub id: Uuid,
    pub data: serde_json::Value,
    ...

}

...

此代码报告数据字段有一些问题

pub data: serde_json::Value
    ^^^^ the trait `diesel::Expression` is not implemented for `Value`

我对铁 rust 和柴油是新手，我不知道它是如何实现的.我以为Serde_json就是我所需要的，但我想我还缺少了其他东西.
