Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Buffers(&'a [iovec])

Register buffer, then use the already registered buffer in ReadFixed and WriteFixed.

Files(&'a [RawFd])

Register file descriptor, then use the already registered fd in Target::Fixed.

EventFd(RawFd)

Register eventfd.
