How to provide my own binding?

[yujonglee]

I need addStreamOutput, but we don't have it in the generated bindings.

objc2/framework-crates/objc2-screen-capture-kit/translation-config.toml

Lines 7 to 8 in cd299d2

	# Needs `dispatch_queue_t`
	class.SCStream.methods."addStreamOutput:type:sampleHandlerQueue:error:".skipped = true

We need #77 to be resolved to get dispatch_queue_t supported.

But since sampleHandlerQueue: dispatch_queue_t? is optional, I wonder if I can get addstreamoutput binding working without waiting for dispatch_queue_t support.

Not sure what is needed to use my own binding alongside objc2. Any input would be appreciated.

You can do something like this:

fn addStreamOutput_type_sampleHandlerQueue_error(
    stream: &SCStream,
    output: &ProtocolObject<dyn SCStreamOutput>,
    r#type: SCStreamOutputType,
    sample_handler_queue: dispatch_queue_t,
) -> Result<(), Retained<NSError>> {
    unsafe { msg_send![stream, addStreamOutput: output, type: r#type, sampleHandlerQueue: sample_handler_queue, error: _] }
}

I'll leave this open to document this better (since it's a common question ;) ).

FYI, I added support for addStreamOutput:type:sampleHandlerQueue:error: in 91a74f3 (will be released in the next version).

Still need to add better docs for how to add the manual binding, so I'll keep this issue open for now.
