Serializing $value enum variant doesn't work #429
Description
Cargo.toml:
[package]
name = "quick-xml-test"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
serde = { version = "1.0.139", features = ["derive"] }
quick-xml = { version = "0.23.0", features = ["serialize" ] }src/main.rs:
use serde::{Deserialize, Serialize};
#[derive(Debug, Deserialize, Serialize)]
enum State {
A,
B,
C,
}
#[derive(Debug, Deserialize, Serialize)]
struct StateOuter {
#[serde(rename = "$value")]
state: State,
}
#[derive(Debug, Deserialize, Serialize)]
pub struct Root {
state: StateOuter,
}
impl Root {
pub fn new() -> Self {
Self { state: StateOuter { state: State::B } }
}
}
fn main() {
let xml = "<root><state>B</state></root>";
println!("Deserialized: {:?}", quick_xml::de::from_str::<Root>(&xml));
let root = Root::new();
println!("Serialized: {:?}", quick_xml::se::to_string(&root));
}Output:
Deserialized: Ok(Root { state: StateOuter { state: B } })
Serialized: Ok("<Root><state><B/></state></Root>")
Expected output:
Deserialized: Ok(Root { state: StateOuter { state: B } })
Serialized: Ok("<Root><state>B</state></Root>")
As you can see deserialization works, but serialization does not.
