powerio

powerio is the core Rust crate for parsing power system case files into a typed Network, retaining same format source text where the reader supports it, and converting through the format neutral model. The workspace README has the full format matrix and language bindings.

use powerio::{TargetFormat, parse_file};

let parsed = parse_file("case14.m", None)?;
let net = parsed.network;
let converted = net.to_format(TargetFormat::PowerModelsJson);
std::fs::write("case14.json", converted.text)?;

The workspace README covers the CLI, Python package, C ABI, matrix builders, and validation suite: https://github.com/eigenergy/powerio.
