lirays 0.1.0

Python client for LiRAYS-SCADA, backed by the local Rust implementation

lirays Python client

Python client for LiRAYS-SCADA that wraps the local Rust client implementation from clients/rust-client.

Design

• Rust extension built with PyO3.
• Local path dependency on ../rust-client (does not pull the client from crates.io).
• Blocking Python API for ergonomic usage while Rust runs async internally.
• Includes .pyi stubs and py.typed for typing support.

Build and install (dev)

cd clients/python-client
maturin develop

Build wheel

cd clients/python-client
maturin build --release

Quick usage

from lirays import Client, FloatVar

client = Client.connect("127.0.0.1", 8245, tls=False)
client.create_folders(["demo_py"], timeout_ms=8000)
client.create_float_variables([FloatVar(name="signal")], parent_id="/demo_py", timeout_ms=8000)
values = client.get_values(["/demo_py/signal"], timeout_ms=8000)
print(values)
client.disconnect()
