Curve support zmq::CurveKeyPair::new(); #401
Description
Hi I am running on debian 12,5
I have a zeromq python client script working fine that includes the line
context = zmq.Context()
public_key, secret_key = zmq.curve_keypair()
this script works fine and i need to translate it to rust
but I get errors when doing
// Generate curve keypair
let keypair_result = zmq::CurveKeyPair::new();
I get the error
Err(Operation not supported)
Is the a feature I need to enable. I can see one from the docs
I am using versions
zmq = { version = "0.10", optional = true }
zmq-sys = { version = "0.12.0", optional = true }
Thanks

My pr fixes it: #400

Is this getting fixed in 0.10.0? Seems like a lot of time has gone by and still get Err on the call, but if I back down to the following config
[dependencies] zmq = { version = "0.9.2", features = ["vendored"] }
Then it seems to work.

Is there any chance that #400 gets merged?
In my project it is mandatory to use CurveZMQ and I'm now forced to go back to version 0.9.2 of the zmq crate.

I also need this merged, and am currently running off the #400 branch. What's the hold up here?

If you're looking for an alternative: OMQ.rs is a pure-Rust, ZMQ-compatible implementation with native CURVE support, including keypair generation. It keeps libzmq-style socket ergonomics without the libzmq build pain, follows the same IO-thread architecture with linear scaling, has benchmarked higher throughput and lower latency in common cases, and adds an
lz4+tcp://compression transport.
