tuple-space-client - HTTP based Async Tuple Space client for Rust

What is a Tuple Space

A tuple space is a method for coordinating data between different processes in an asynchronous manner. Processes write tuples of data to the tuple space and then read or remove data from the tuple space using a tuple as template to match against.

This client is based on the tuple-space crate. The corresponding tuple-space-server is used to store tuples.

Usage

extern crate tokio;
extern crate tuple_space;
extern crate tuple_space_client;

use tuple_space::tuple::Tuple;
use tuple_space_client::client::Client;

#[tokio::main]
async fn main() {
    let client = Client::builder().build("http://localhost:8000").unwrap();

    let tuple = Tuple::builder().string("Number").integer(5).build();

    client.write(&tuple).await.unwrap();
    println!("Wrote: {}", tuple);

    let query_tuple = Tuple::builder()
        .string("Number")
        .any_integer()
        .build();

    println!("Query: {}", query_tuple);
    let read_tuple = client.read(&query_tuple).await.unwrap().unwrap();
    println!("Read {}", read_tuple);

    println!("Query: {}", query_tuple);
    let take_tuple = client.take(&query_tuple).await.unwrap().unwrap();
    println!("Take {}", take_tuple);

    println!("Query: {}", query_tuple);
    let no_tuple = client.take(&query_tuple).await.unwrap();
    println!("Take {:?}", no_tuple);
}
