You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ieee8021x.rs
    path of file: ./repos/nmstate/rust/src/lib/nm/nm_dbus/connection
    
    the code of the file until where you have to start completion: use std::collections::HashMap;
use std::convert::TryFrom;

use serde::Deserialize;

use super::super::{
    connection::DbusDictionary, ErrorKind, NmError, ToDbusValue,
};

const GLIB_FILE_PATH_PREFIX: &str = "file://";

#[derive(Debug, Clone, PartialEq, Default, Deserialize)]
#[serde(try_from = "DbusDictionary")]
#[non_exhaustive]
pub struct NmSetting8021X {
    pub identity: Option<String>,
    pub priva
    
    pub(crate) fn fill_secrets(&mut self, secrets: &DbusDictionary) {
        if let Some(v) = secrets.get("private-key-password") {
            match String::try_from(v.clone()) {
                Ok(s) => {
                    self.private_key_password = Some(s);
                }
                Err(e) => {
                    log::warn!(
                        "Filed to convert private_key_password: \
                        {:?} {:?}",
                        v,
                        e
                    );
                }
            }
        }
