Issue when decoding a simple Enum with no member values. #695
Description
Bincode version: 2.0.0-rc3
I'm facing an issue when using bincode's serde facing serialization/deserialization with simple Enums.
Namely I always get UnexpectedEnd { additional: 1 } error when trying to decode the enum.
The enum in question:
#[derive(Clone, Debug, Serialize, Deserialize, PartialEq, Eq)]
pub enum MessageModule {
Reconfiguration,
Protocol,
StateProtocol,
Application,
}
The unit test used to verify this behaviour:
#[test]
pub fn test_message_mod_serialization() -> Result<()> {
let msg_mod = MessageModule::Protocol;
let vec = bincode::serde::encode_to_vec(&msg_mod, bincode::config::standard())?;
let mod_bytes = Bytes::from(vec);
println!("Mod bytes {:x?}", mod_bytes);
let (de_ser_msg_mod, msg_mod_size): (MessageModule, usize) = bincode::serde::decode_borrowed_from_slice(mod_bytes.as_ref(), bincode::config::standard())?;
assert_eq!(de_ser_msg_mod, msg_mod);
Ok(())
}
Bytes::from is using the bytes crate.
Expected behaviour: The decoded message module should match the encoded one.
Observed behaviour: Error: UnexpectedEnd { additional: 1 }
