Async OPC-UA Nodes

Part of async-opcua, a general purpose OPC-UA library in rust.

This library defines types used mainly in the async-opcua-server library as part of in-memory node managers, but also utilities for importing NodeSet2 XML files to Rust.

Primarily, this library defines a type for each OPC-UA NodeClass Object, Variable, Method, View, ObjectType, VariableType, DataType, and ReferenceType, as well as builders for all of these. There's also a common enum over all of these NodeType.

A few other common types are also defined here, such as the TypeTree trait, used in the server to provide the server with a view of all the types defined on the server, and the NodeSet2Import type, used to import NodeSet2 files into memory.

Features

• xml adds support for reading NodeSet2 XML files into NodeType.
