objc2-metal crate lacks makeLibrary(data:)

[mxpv]

It looks like makeLibrary(data:) is not generated for objc2-metal crate. It is useful to load Metal's libraries from data in memory. This likely might require some further bindings to Dispatch Data (to create dispatch_data_t).

Here is an example of use case: https://github.com/gfx-rs/metal-rs/blob/2b7240232ca8621f22d2df58718919f67562feca/src/device.rs#L1727

Indeed it isn't, since like you said, it requires types from libdispatch, and that isn't yet mapped.

You can work around this by using msg_send_id! with its error conversion support, like the following:

type dispatch_data_t = *mut AnyObject;
// Create the dispatch data manually
let data: dispatch_data_t = dispatch_data_create(...);

let library: Result<Retained<MTLLibrary>, Retained<NSError>> = unsafe {
    msg_send_id![self, newLibraryWithData: data, error: _]
};

Feel free to ask further questions, but otherwise I'm going to close this, since it's already tracked in #77 (and the larger work is tracked in #556).
