Function config 

pub async fn config(field: &str) -> Result<Option<ConfigOption>, ConfigError>

• Ok(None) if the field doesn’t exist.
• Err(ConfigError) if there is an error during retrieval.

let config_value = config("language").await?;
if let Some(option) = config_value {
    println!("Config value: {}", option);
}

Errors

Returns ConfigError::DB if there is an issue with the database connection.
