Class IoUringSharedIovArray

java.lang.Object
io.netty.channel.uring.IoUringSharedIovArray
final class IoUringSharedIovArray extends java.lang.Object
The iovec memory of an IoUringIoHandler, shared by all writes until the next submit.

Each write gets its own empty IovArray that starts after the entries of the previous writes, so the IOV_MAX limit of an IovArray applies to each write and not to all of them together.
