Unable to serialize a struct that deserialization works for #654
Description
I'm trying to serialize/deserialize some data that an API responds with. This is what the XML from the API looks like:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<LoginResponse xmlns="urn:vim25">
<returnval>
<userName>username_here</userName>
<loggedInAt>datetime_here</loggedInAt>
</returnval>
</LoginResponse>
</soapenv:Body>
</soapenv:Envelope>And this is my code:
#[derive(Deserialize, Debug, Serialize)]
#[serde(rename = "soapenv:Envelope")]
pub struct SoapResponse {
#[serde(rename = "@xmlns:soapenc")]
soapenc: Option<String>,
#[serde(rename = "@xmlns:soapenv")]
soapenv: Option<String>,
#[serde(rename = "@xmlns:xsd")]
xsd: Option<String>,
#[serde(rename = "@xmlns:xsi")]
xsi: Option<String>,
#[serde(rename = "$value")]
pub body: SoapBody,
}
#[derive(Deserialize, Debug, Serialize)]
pub struct SoapBody {
#[serde(rename = "$value")]
pub response_type: Response,
}
#[derive(Deserialize, Debug, Serialize)]
pub enum Response {
#[serde(rename = "LoginResponse")]
LoginResponse {
#[serde(rename = "@xmlns")]
xmlns: String,
#[serde(rename = "$value")]
returnval: LoginResponse,
},
#[serde(rename = "Other")]
SomeOther {},
}
#[derive(Deserialize, Debug, Serialize)]
#[serde(rename_all = "camelCase")]
pub struct LoginResponse {
logged_in_at: String,
user_name: String,
}Deserialization works fine. However, when I try to serialize a structure like this:
use quick_xml::se::to_string;
let thing = SoapResponse {
soapenc: None,
soapenv: None,
xsd: None,
xsi: None,
body: {
SoapBody {
response_type: Response::LoginResponse {
xmlns: "urn:vim25".into(),
returnval: LoginResponse {
logged_in_at: "example".into(),
user_name: "example".into(),
},
},
}
},
};
let thing = to_string(&thing);
dbg!(&thing);I get
Err(
Unsupported(
"serialization of struct `SoapBody` is not supported in `$value` field",
),
)
What could be the reason that causes this?
