I have the following simple schema:
@0x8fe87a03768154e9;
enum Side {
buy @0;
sell @1;
}
struct TradeMessage {
time @0 : Float64;
tradeId @1 : Int64;
side @2 : Side;
size @3 : Float64;
price @4 : Float64;
}
struct Level1BookUpdateMessage {
time @0 : Float64;
best_bid_qty @1 : Float64;
best_bid_px @2 : Float64;
best_ask_qty @3 : Float64;
best_ask_px @4 : Float64;
}
which I am loading as follows using pycapnp 1.0.0 on MacOS 11.4 running
Python 3.8:
import capnp
from pathlib import Path
capnp_path = Path(__file__).parent / '../../../../capnp/serenity-fh.capnp'
capnp_def = capnp.load(capnp_path)
It fails on load with the following error. Any ideas on what I might be
doing wrong?
