Rust ZeroMQ bindings.

Documentation Release Notes

Installation

Currently, rust-zmq requires ZeroMQ 3.2 or newer. For example, on recent Debian-based distributions, you can use the following command to get the prerequiste headers and library installed:

apt install libzmq3-dev

If your OS of choice does not provide packages of a new-enough libzmq, you will first have to install it from source; see https://github.com/zeromq/libzmq/releases.

rust-zmq uses cargo to install. Users should add this to their Cargo.toml file:

[dependencies]
zmq = "0.8"

Install for developers:

% git clone https://github.com/erickt/rust-zmq
% cd rust-zmq
% cargo build

The build normally uses pkg-config to find out about libzmq's location. If that is not available, the environment variable LIBZMQ_PREFIX (or alternatively, LIBZMQ_LIB_DIR and LIBZMQ_INCLUDE_DIR) can be defined to avoid the invocation of pkg-config.

Usage

rust-zmq is a pretty straight forward port of the C API into Rust:

extern crate zmq;

fn main() {
    let ctx = zmq::Context::new();

    let mut socket = ctx.socket(zmq::REQ).unwrap();
    socket.connect("tcp://127.0.0.1:1234").unwrap();
    socket.send_str("hello world!", 0).unwrap();
}

You can find more usage examples in https://github.com/erickt/rust-zmq/tree/master/examples.
