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: cmd.rs
    path of file: ./repos/spyglass/crates/tauri/src
    
    the code of the file until where you have to start completion: use std::collections::HashMap;
use std::path::Path;
use std::str::FromStr;
use std::sync::{atomic::Ordering, Arc};

use shared::response::{DefaultIndices, SearchResults};
use tauri::api::dialog::FileDialogBuilder;
use tauri::State;
use tauri::{ClipboardManager, Manager};

use crate::constants::TabLocation;
use crate::current_version;
use crate::window::navigate_to_tab;
use crate::PauseState;
use crate::{open_fo
    
pub async fn revoke_connection(win: tauri::Window, id: &str, account: &str) -> Result<(), String> {
    log::debug!("revoking connection: {}@{}", account, id);
    if let Some(rpc) = win.app_handle().try_state::<rpc::RpcMutex>() {
        let rpc = rpc.lock().await;
        if let Err(err) = rpc
            .client
            .revoke_connection(id.to_string(), account.to_string())
            .await
        {
            return Err(err.to_string());
        } else {
            let _ = win.emit(ClientEvent::RefreshConnections.as_ref(), true);
        }
    }

    Ok(())
