RemotePacketSizeCounter

Calculates the size of remote packet data in bytes, given the packet data. Used in https://github.com/PysephWasntAvailable/PacketProfiler.

Buffer values at least 100 bytes long are estimated using Roblox's transparent Zstandard network compression. GetPacketSizeDetails and GetDataByteSizeDetails return both the estimated transmitted size and the uncompressed serialized size:

local details = PacketSizeCounter.GetPacketSizeDetails({
	RunContext = "Server",
	RemoteType = "RemoteEvent",
	PacketData = { buffer.create(1024) },
})

print(details.Size)
print(details.UncompressedSize)
print(details.CompressionSavings)
print(details.CompressedBufferCount)

Compressed sizes are estimates because Roblox does not expose its exact remote serialization or transport framing. The existing GetPacketSize and GetDataByteSize functions return the estimated compressed size.
