opus::Decoder and opus::Encoder fail, need python method how to get the error?

example in rust StreamReader decode packet data error

                let bytes_read = decoder.decode_float(
                    &packet.data,
                    &mut pcm_buf,
                    /* Forward Error Correction */ false,
                );
                match bytes_read {
                    Err(err) => {
                        println!("decode error:{}", err);
                        if pcm_tx.send(Err(err.into())).is_err() {
                            break;
                        };
                        break;
                    }
                    Ok(n) => {
                        if pcm_tx.send(Ok(pcm_buf[..n].to_vec())).is_err() {
                            break;
                        }
                    }
                }

want to get the error in python method in try ... except ... get error to do something , e.g.:

try:
   pcm = OpusStreamReader(24000).read_pcm()
except OpusDecoderException as e:
   print(f"opus decode error: {e}")

Could you provide some small reproducible example and detail the current behavior vs what yo would like to see? Thanks.
