IO Pipe Library

IO Pipe is a thread-safe Rust library for creating multi-writer and single-reader pipelines. It's ideal for scenarios where you need to write bytes from multiple threads and read them from a single thread.

Features

Thread-safe communication between writers and readers
Support for both synchronous and asynchronous operations (via feature flags)
Easy-to-use API for creating pipes
Zero dependencies (for core functionality)

Installation

Add this to your Cargo.toml:

[dependencies]
io-pipe = "0.x.x"

For async support, enable the async feature:

[dependencies]
io-pipe = { version = "0.x.x", features = ["async"] }

Usage

Synchronous API

Single-thread example:

use std::io::{read_to_string, Write};
use io_pipe::pipe;

fn main() {
    let (mut writer, reader) = pipe();
    writer.write_all("hello".as_bytes()).unwrap();
    drop(writer);

    assert_eq!("hello".to_string(), read_to_string(reader).unwrap());
}

Multi-thread example:

use std::io::{read_to_string, Write};
use std::thread::spawn;
use io_pipe::pipe;

fn main() {
    let (mut writer, reader) = pipe();
    spawn(move || {
        writer.write_all("hello".as_bytes()).unwrap();
    });

    assert_eq!("hello".len(), read_to_string(reader).unwrap().len());
}

Asynchronous API

use io_pipe::async_pipe;
use futures::io::{AsyncWriteExt, AsyncReadExt};
use futures::executor::block_on;

fn main() {
    block_on(async {
        let (mut writer, mut reader) = async_pipe(1024);

        writer.write_all(b"hello").await.unwrap();
        drop(writer);

        let mut buffer = String::new();
        reader.read_to_string(&mut buffer).await.unwrap();
        assert_eq!("hello", buffer);
    });
}
