Cross-platform local IPC for roam.

This crate provides a unified API for local inter-process communication:

• Unix: Uses Unix domain sockets
• Windows: Uses named pipes

Usage

Server

use roam_local::LocalListener;

// On Unix: path like "/tmp/my-app.sock"
// On Windows: pipe name like r"\\.\pipe\my-app"
let mut listener = LocalListener::bind(endpoint)?;

loop {
    let stream = listener.accept().await?;
    // stream implements AsyncRead + AsyncWrite
    tokio::spawn(handle_connection(stream));
}

Client

use roam_local::connect;

let stream = connect(endpoint).await?;
// stream implements AsyncRead + AsyncWrite

Platform Differences

The main API is the same across platforms, but there are some differences:

• Endpoint format: Unix uses filesystem paths, Windows uses pipe names (e.g., \\.\pipe\my-app)
• Stream types: On Unix, both client and server use UnixStream. On Windows, the client uses NamedPipeClient and the server uses NamedPipeServer. Both implement AsyncRead + AsyncWrite.
• Cleanup: Unix sockets leave files that may need manual cleanup. Windows named pipes are automatically cleaned up when all handles close.
