Converter

ib_interface.protobuf.converter

Convert between Protobuf messages and ib-interface dataclasses.

This module is the bridge that allows ib-interface to maintain its dataclass-based API while internally using Protobuf for communication.

Design Philosophy:

  • Protobuf is used for wire protocol only
  • All internal state uses ib-interface dataclasses
  • User-facing API never exposes Protobuf types

ProtobufConverter​

Bidirectional converter between Protobuf and dataclasses.

Convert Protobuf Order to ib-interface Order dataclass.

order_to_proto​

def order_to_proto(order: Order) -> OrderProto

Convert ib-interface Order dataclass to Protobuf Order.

contract_from_proto​

def contract_from_proto(proto: ContractProto) -> Contract

Convert Protobuf Contract to ib-interface Contract dataclass.

bar_data_from_proto​

def bar_data_from_proto(proto: BarProto) -> BarData
