Paladin in 2 sentences

Paladin is a Rust library that aims to simplify writing distributed programs. It provides a declarative API, allowing developers to articulate their distributed programs clearly and concisely, without thinking about the complexities of distributed systems programming.

Features

Example

Below is a (contrived) example of how a typical Paladin program looks.

#[tokio::main]
async fn main() {
    let stream = IndexedStream::from([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
    // Compute the fibonacci number at each element in the stream.
    let fibs = stream.map(FibAt);
    // Sum the fibonacci numbers.
    let sum = fibs.fold(Sum);

    // Run the computation.
    let result = sum.run(&runtime).await.unwrap();
    assert_eq!(result, 143);
}

In this example program, we define an algorithm for computing the fibonacci number at each element in a stream, after which we sum the results. Behind the scenes, Paladin will distribute the computations across the cluster and return the result back to the main thread.
