Add missing getter in SubmitArgs.

[sugarraysam]

Need to expose the SubmitArgs::get_args() getter because I can't implement missing liburing cqe helpers like this one otherwise.

Makes it easier than working directly with sys::io_uring_getevents_arg.

    // Expose missing cqes only enter methods from `liburing`.
    pub fn wait_cqes_timeout(&self, min_complete: u32, timeout: Duration) -> Result<usize> {
        let flags = sys::IORING_ENTER_EXT_ARG | sys::IORING_ENTER_GETEVENTS;

        let ts = types::Timespec::from(timeout);
        let args = types::SubmitArgs::new().timespec(&ts);

        unsafe {
            self.ring
                .submitter()
                .enter(0, to_complete, flags, Some(&args.args)) // <--- private field !!
        }
    }

We cannot expose private types

[sugarraysam]

That is very true. I found another issue after all, where all of the io_uring_enter flags are defined in the sys:: module, but the module is private.

What do you think would be the best way to expose these flags to developers?

@quininer how about this ? #364

You can add a repr(transparent) to SubmitArgs , then I think passing SubmitArgs to .enter() will be legal.

Works like a charm ! Fixed and tested:

$ cargo test
$ cargo run -p io-uring-test

Thank you!
