fn recv_io_uring_raw(
    &mut self,
    ctx: Ctx,
    info_buf: &[u8]
) -> Result<Option<usize>>

The raw syscall invoked by the kernel when the scheme is requested to have an io_uring attached. This function will most likely not be needed directly, but rather the convenience wrapper recv_io_uring.

fn recv_io_uring(
    &mut self,
    ctx: Ctx,
    info: &IoUringRecvInfo
) -> Result<Option<usize>>

Called by the kernel when a userspace program has invoked attach_iouring onto an fd owned by this scheme. The return value is expected to be zero in case the scheme accepted the io_uring, or one otherwise.
