Estou tentando usarDiesel para consultar um banco de dados MySQL e exibir os resultados com um modelo de guidão comFoguete.

Eu tenho isso emmodels.rs

#[derive(Queryable, Serialize)]
pub struct Post {
    pub id: i32,
    pub title: String,
    pub text: String,
    pub published: bool,
}

cargo run gera isso:

  --> src/main.rs:69:5
   |
69 |     Template::render("index", &results)
   |     ^^^^^^^^^^^^^^^^ the trait `serde::ser::Serialize` is not implemented for `tasty::models::Post`
   |
   = note: required because of the requirements on the impl of `serde::ser::Serialize` for `std::vec::Vec<tasty::models::Post>`
   = note: required by `rocket_contrib::Template::render`

No meu Cargo.toml, tenho o seguinte:

[dependencies]
chrono = "0.3.0"
rocket = "0.2.8"
rocket_codegen = "0.2.8"
serde = "1.0.8"
serde_derive = "1.0.8"
serde_json = "1.0.2"
mysql = "11.1.2"
diesel = { version = "0.13.0", features = ["mysql","chrono"] }
diesel_codegen = { version = "0.13.0", features = ["mysql"] }
dotenv = "0.10.0"

[dependencies.rocket_contrib]
version = "*"
default-features = false
features = ["handlebars_templates"]

Eu li que o Diesel não suportaSerialize no momento, mas não tenho certeza.
