How to use convert_from_registers instead with different data types?

How to use convert_from_registers instead of BinaryPayloadDecoder with multiple different data types?
Old code:

result = self.client.read_holding_registers(0x0200, count=21,  slave=1)
decoder = payload.BinaryPayloadDecoder.fromRegisters(result.registers, byteorder=constants.Endian.BIG, wordorder=constants.Endian.LITTLE)
voltage = decoder.decode_32bit_int()
current = decoder.decode_32bit_int()
temperature = decoder.decode_16bit_int()
...

Please see the examples.

In example used deprecated BinaryPayloadDecoder.

That is only one example (which is still there because the payload is still there), there are others.

Hi

I have a device that has a large amount of registers, I can't read and decode each register one by one.
I'm reading 15 registers but inside there are float32, uint32 and uint64 and I'm wondering how to decode?
My intuition tells me:

u16 = client.convert_from_registers(rr.registers[offset:offset+1] ...
offset += 1
# un uint32
u32 = client.convert_from_registers(rr.registers[offset:offset+2] ....
offset += 2
# un float32
f32 = client.convert_from_registers(rr.registers[offset:offset+2] ....

Thank you

It is not only your intuition but also the documentation.

You need to call from_registers multiple times.
