PolyXML

The Universal Native XML Data-Binding Engine

Welcome to PolyXML

PolyXML is a high-performance native XML engine written in Rust for ultra-fast, streaming XML serialization and deserialization. It bridges raw XML directly to strongly-typed data structures across modern language runtimes with zero unnecessary allocations.

While web ecosystems shifted toward JSON and Protocol Buffers, mission-critical infrastructure in defense & aerospace (UCI), finance (ISO 20022, FIXML), and healthcare (HL7) remains deeply reliant on XML. PolyXML breaks down language barriers and eliminates legacy performance penalties by providing one unified, native Rust engine for all tech stacks.

Supported Ecosystems

Native zero-copy core engine via polyxml on crates.io. Monomorphized, fast streaming parser.

Accelerates Python dataclasses and Pydantic v2 models via PyO3 (abi3-py312). 10x–30x faster than pure Python XML parsers.

Zero-overhead modern C++20 header-only wrapper (polyxml.hpp) with RAII memory management, designed for avionics, robotics, and defense.

High-throughput Cgo wrapper providing polyxml.Deserialize and polyxml.Serialize, replacing Go's slow reflection-based encoding/xml.

Native Node.js addon compiled via napi-rs with full TypeScript definitions (index.d.ts), ideal for high-throughput microservices.

Java 22+ Foreign Function & Memory API (JEP 454) binding directly to off-heap memory with zero JNI boilerplate.
