A crate with mock IO stream and listener implementations.

Usage

Add mock-io in your Cargo.toml's dependencies section:

[dependencies]
mock-io = "0.3"

Here is a sample usage of this crate:

use mock_io::sync::{MockListener, MockStream};

let (listener, handle) = MockListener::new();

thread::spawn(move || {
    let mut stream = MockStream::connect(&handle).unwrap();
    stream.write(&1u64.to_be_bytes()).unwrap();
    stream.write(&2u64.to_be_bytes()).unwrap();
});

while let Ok(mut stream) = listener.accept() {
    let mut buf = [0; 8];

    stream.read(&mut buf).unwrap();
    assert_eq!(1u64.to_be_bytes(), buf);
    
    stream.read(&mut buf).unwrap();
    assert_eq!(2u64.to_be_bytes(), buf);
}

Features

  • sync: Enables sync mock IO stream and listener
    • Enabled by default
  • async-futures: Enables async mock IO stream and listener (using futures::io::{AsyncRead, AsyncWrite})
    • Disabled by default
  • async-tokio: Enables async mock IO stream and listener (using tokio::io::{AsyncRead, AsyncWrite})
    • Disabled by default

Note: Some functions in this crate returns a Future. So, you'll need an executor to drive Futures returned from these functions. async-std and tokio are two popular options.
