could not find `options` in `mongodb` Rust Lang

Question

I am trying to connect to mongodb using in rust using mongodb library

here is the code

use actix_web::{App, HttpServer};
use mongodb::{Client, options::ClientOptions};

#[actix_rt::main]
async fn main() -> std::io::Result<()> {
// Parse a connection string into an options struct.
let mut client_options = ClientOptions::parse("mongodb://localhost:27017")?;

client_options.app_name = Some("My App".to_string());

let client = Client::with_options(client_options)?;

for db_name in client.list_database_names(None)? {
    println!("{}", db_name);
}

    HttpServer::new(move || {
        App::new()
    })
    .bind("127.0.0.1:3000")?
    .run()
    .await
}

I am getting following errors

error[E0432]: unresolved import mongodb::options
use mongodb::{Client, options::ClientOptions}; | ^^^^^^^ could not find options in mongodb
let client = Client::with_options(client_options)?; | ^^^^^^^^^^^^ function or associated item not found in std::sync::Arc<r2d2_mongodb::mongodb::ClientInner>

Using current version of mongodb. **MongoDB shell version v4.2.5** — Niraj Gawande, Apr 24 '20 at 04:35
that not the version I want, what is your crate version https://crates.io/crates/mongodb ? — Stargateur, Apr 24 '20 at 12:10

I put start in the version number in Cargo.toml. Changing it to latest version number solved issue.
