# DNP3

Rust implementation of DNP3 (IEEE 1815) with idiomatic bindings for C, C++, .NET, and Java.

# Features

- Subset Level 3 master and outstation components in a single library

  - Official support for: Windows x64 and Linux x64, AArch64, ARMv7 and ARMv6
  - Unofficial support: MacOS, PowerPC, MIPS, FreeBSD, and others
