Continuous waiting in Rust can be enhanced by using various techniques and libraries. Some of the ways to enhance continuous waiting in Rust are:

1. Using Futures: Rust has an async-await mechanism that makes it easy to perform asynchronous operations. Libraries like Futures and Tokio provide a wide range of utilities to schedule and manage async tasks, which can be used to improve continuous waiting.

2. Using Timers: Rust's standard library has a Timer module that can be used to schedule timers that can be used to wait for a specific amount of time. This module can be used in conjunction with async-await features to perform non-blocking operations.

3. Using Channels: Rust's standard library has a Channel module that can be used to create channels between the different threads, which can be used to communicate and coordinate tasks. This can be used for managing tasks and signalling completion.

4. Using Flags: Rust's standard library has a range of atomic operations that can be used to create flags that store the status of the operation, which can be checked periodically by the waiting thread.

5. Using Asyncio: Asyncio is a third-party library that brings the asyncio model of Python to Rust. The library provides a high-level interface for performing async IO operations that can be used for enhancing continuous waiting.
