Missing Network Crate

[zamderax]

NSNetService in Foundation has all been deprecated:

• See official documentation here: https://developer.apple.com/documentation/foundation/nsnetservice
• See https://forums.developer.apple.com/forums/thread/682744

It's been succeeded by the Network Framework:
https://developer.apple.com/documentation/network?language=objc

I can only see a NetworkExtension autogenerated crate; which is completely different than Network

Question:

1. How can I generate the Network crate/feature since it's missing
2. Alternatively, can I call these methods without the Network crate on version 0.5.2?

Yeah, see #556, more work is needed to figure out how memory management should work.

can I call these methods without the Network crate on version 0.5.2?

You should be able to, you'll have to write the extern "C" definitions yourself, but it's a lot of work. For an API like nw_browser_create, to take a random example, the C header contains:

NW_RETURNS_RETAINED nw_browser_t
nw_browser_create(nw_browse_descriptor_t descriptor,
				  _Nullable nw_parameters_t parameters);

So in Rust you'd write something like:

// --- Declare protocols that is used in Network

extern_protocol!(
    unsafe trait OS_nw_browser: NSObjectProtocol {}
    unsafe impl ProtocolType for dyn OS_nw_browser {}
);
type nw_browser_t = ProtocolObject<dyn OS_nw_browser>;

extern_protocol!(
    unsafe trait OS_nw_parameters: NSObjectProtocol {}
    unsafe impl ProtocolType for dyn OS_nw_parameters {}
);
type nw_parameters_t = ProtocolObject<dyn OS_nw_parameters>;

extern_protocol!(
    unsafe trait OS_nw_browse_descriptor: NSObjectProtocol {}
    unsafe impl ProtocolType for dyn OS_nw_browse_descriptor {}
);
type nw_browse_descriptor_t = ProtocolObject<dyn OS_nw_browse_descriptor>;

// --- Declare the actual function prototype

extern "C" {
    fn nw_browser_create(
        descriptor: &nw_browse_descriptor_t,
        parameters: Option<&nw_parameters_t>,
    ) -> *mut nw_browser_t;
}

// --- Usage

// SAFETY: Uses `Retained::from_raw` because of `NW_RETURNS_RETAINED`.
let browser = unsafe { Retained::from_raw(nw_browser_create(descriptor, parameters)) };

I think, at least, I doubt I'm familiar enough with the Network framework to help you out further, though feel free to ask!
