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: list.rs
    path of file: ./repos/fluvio/crates/fluvio-hub-util/src/cmd
    
    the code of the file until where you have to start completion: use std::sync::Arc;
use std::fmt::Debug;

use clap::Parser;
use anyhow::Result;

use fluvio_extension_common::Terminal;
use fluvio_extension_common::OutputFormat;
use crate::HUB_API_CONN_LIST;

use super::get_pkg_list;

/// List all available SmartConnectors
#[derive(Debug, Parser)]
pub struct ConnectorHubList
    
        fn content(&self) -> Vec<Row> {
            self.0
                .iter()
                .map(|e| {
                    Row::from([
                        Cell::new(e.pkg_name()).set_alignment(CellAlignment::Left),
                        Cell::new(&e.visibility).set_alignment(CellAlignment::Left),
                    ])
                })
                .collect()
        }
