Windows Shared Memory

Windows IPC library using shared memory. Supports 32-bit/64-bit cross-process communication.

Installation

[dependencies]
windows_shared_memory = "0.1.5"

Usage

use windows_shared_memory::{Server, Client, ReceiveMessage};

// Server
let server = Server::new(None).unwrap();
server.send(b"Hello").unwrap();
if let ReceiveMessage::Message(msg) = server.receive(Some(1000)) {
    println!("{}", msg);
}

// Client (separate process)
let client = Client::new(None).unwrap();
if let ReceiveMessage::Message(msg) = client.receive(Some(1000)) {
    println!("{}", msg);
}
client.send(b"Hi").unwrap();

Custom path:

let server = Server::new(Some("Local\\MyShm")).unwrap();
let client = Client::new(Some("Local\\MyShm")).unwrap();

Custom Buffer Size

// Server with 64KB buffer
let server = Server::with_buffer_size(None, 64 * 1024).unwrap();

// Client auto-detects buffer size from server
let client = Client::new(None).unwrap();
println!("Buffer: {} KB", client.buffer_size() / 1024);

API

ReceiveMessage: Message(String), Timeout, Exit, MessageError(String)
