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: adfgx.rs
    path of file: ./repos/CaptfEncoder/CaptfEncoder-V3/encoding/src/classical
    
    the code of the file until where you have to start completion: use std::collections::HashMap;

use super::internal::anyhow::*;
use super::internal::anyhow::Result;

use crate::EncodingResult;
use crate::get_option;

pub fn encode(input: &str, options: Option<HashMap<String, String>>) -> Result<EncodingResult> {
    use super::internal::ciphers::{Cipher
    
pub fn encode(input: &str, options: Option<HashMap<String, String>>) -> Result<EncodingResult> {
    use super::internal::ciphers::{Cipher, ADFGX};

    let key = get_option("key", &options, "");
    let keyword =  get_option("keyword", &options, "");

    let input = input.to_uppercase();


    let encoder = ADFGX::new(key.as_str(), keyword.as_str());

    let result = encoder.encipher(&input).or_else(|e| Err(anyhow!("{:?}", e)))?;

    let result = EncodingResult {
        successed: true,
        val: result,
        message: String::from(""),
    };
    
    Ok(result)
}
