Dining Philosophers --- Async

See dining philosophers for a description of the problem.

As before, you will need a local Cargo installation for this exercise. Copy the code below to a file called src/main.rs, fill out the blanks, and test that cargo run does not deadlock:

rust,compile_fail

# // Copyright 2024 Google LLC
# // SPDX-License-Identifier: Apache-2.0
#
{{#include dining-philosophers.rs:Philosopher}}
    // left_chopstick: ...
    // right_chopstick: ...
    // thoughts: ...
}

{{#include dining-philosophers.rs:Philosopher-think}}

{{#include dining-philosophers.rs:Philosopher-eat}}
{{#include dining-philosophers.rs:Philosopher-eat-body}}
{{#include dining-philosophers.rs:Philosopher-eat-end}}
    // Create chopsticks

    // Create philosophers

    // Make them think and eat

    // Output their thoughts
}

Since this time you are using Async Rust, you'll need a tokio dependency. You can use the following Cargo.toml:

toml

[package]
name = "dining-philosophers-async-dine"
version = "0.1.0"
edition = "2024"

[dependencies]
tokio = { version = "1.26.0", features = ["sync", "time", "macros", "rt-multi-thread"] }

Also note that this time you have to use the Mutex and the mpsc module from the tokio crate.

Can you make your implementation single-threaded?
