Hi guys. I am serializing a struct manually (because of something bigger I need to do) and the result of the serialization is this:
SerializeDyn(
type: "engine_utils::types::registry::tests::Player",
)Now I need to deserialize it back manually.. but I'm having some problems trying to understand how to do that.. Because for now I have this piece of code:
fn deserialize<'de>(deserializer: ron::Deserializer<'de, &mut Vec<u8>>)
{
deserializer.deserialize_struct("SerializeDyn", &["type"], SerializeDynVisitor);
}
struct SerializeDynVisitor;
impl<'de> Visitor<'de> for SerializeDynVisitor {
type Value = Box<dyn Any>;
fn expecting(&self, formatter: &mut std::fmt::Formatter) -> std::fmt::Result {
write!(formatter, "a serialize dyn struct")
}
//Apparently when I deserialize a struct, this is what ends up being called in the visitor
fn visit_map<A>(self, mut map: A) -> Result<Self::Value, A::Error>
where A: serde::de::MapAccess<'de>
{
let entry = map.next_entry::<&str, String>()?; //Here I get the error!
todo!()
}
}But when I do map.next_entry... I get this error:
Err(
InvalidValueForType {
expected: "a borrowed string",
found: "the string \"type\"",
},
)What does this mean? I can't do map.next_entry::<String, String>()? because it panics saying: IdDeserializer may only be used for identifiers but I don't understand what I should do to read the value of the field.
