我是新手，正在学习Rust，并尝试在stackoverflow上搜索以及阅读serde文档https://docs.serde.rs/serde/trait.Serialize.html和https://serde.rs/impl-serialize.html，但是我有些迷茫。
我想使用Tera生成html，但我传递给它的结构体没有实现serde::ser::Serialize trait，我尝试实现它，但是好像不太对。
Cargo.toml 依赖项
serde = "1.0.115"
serde_derive = "1.0.115"
serde-xml-rs = "0.4.0"
tera = "0.7.2"
main.rs
extern crate tera;
#[macro_use]
extern crate serde_derive;
extern crate serde;
use tera::Context;
use serde::ser::{Serialize, SerializeStruct, Serializer};
#[derive(Serialize, Debug)]
struct Person {
firstname: String,
lastname: String,
age: i32,
}
#[derive(Debug)]
struct Attendees {
people: Vec<Person>,
updatedOn: String,
updatedBy: String,
}
impl Serialize for Attendees {
fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
where
S: Serializer,
{
let mut s = serializer.serialize_struct("Person", 3)?;
s.serialize_field("people", &self.people)?;
s.serialize_field("updatedOn", &self.updatedOn)?;
s.serialize_field("updatedBy", &self.updatedBy)?;
s.end()
}
}
fn main() {
let mut context = Context::new();
let mut peeps: Vec<Person> = Vec::new();
let mut attendees = Attendees {
people: peeps,
updatedOn: String::from("today"),
updatedBy: String::from("someone"),
};
context.add("attendees", &attendees);
}
编译器提示：
mytest % cargo run
Compiling mytest v0.1.0 (/home/mike/mytest)
error[E0277]: the trait bound `Attendees: serde::ser::Serialize` is not satisfied
--> src/main.rs:44:29

44 | context.add("attendees", &attendees);
| ^^^^^^^^^^ the trait `serde::ser::Serialize` is not implemented for `Attendees`

我显然错过了什么... 有人可以帮忙吗？
