Curve support zmq::CurveKeyPair::new();

[glennpierce]

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.
