io_uring only.Expand description
Linux io_uring.
This API is very low-level. The main adaptations it makes from the raw
Linux io_uring API are the use of appropriately-sized bitflags, enum,
Result, OwnedFd, AsFd, RawFd, and *mut c_void in place of plain
integers.
Safety
io_uring operates on raw pointers and raw file descriptors. Rustix does not attempt to provide a safe API for these, because the abstraction level is too low for this to be practical. Safety should be introduced in higher-level abstraction layers.
