Is safe use ReadOnlyMemory across lists?

[nathan130200]

I'm working on an send queue to an TCP socket, i will store buffer to send and task completition source, to notify if send is completed or got some error.

I was using raw byte array in queue entry type. But i'm finding solutions to reduce memory usage.

class QueueEntry {
  public byte[] Data { get; init; }
  public TaskCompletitionSource Completition { get; init; }
}

If i set this Data to an existing buffer will peform an copy or will still pass array by reference?
Instead i can use ReadOnlyMemory<byte> to replace byte[]? Since its value type will pass by reference too without data loss?

The (RO)Memory, (like the (RO)Span) just contains the reference to the array, not a copy
