Crate opcua_macros 

Crate containing various procedural macros used by rust OPC-UA.

Attribute Macros

ua_encodable

Derive all the standard encoding traits on this struct or enum. This will derive BinaryEncodable, BinaryDecodable, JsonEncodable, JsonDecodable, XmlEncodable, XmlDecodable, XmlType, and UaEnum if the type is a simple enum.

Derive Macros

BinaryDecodable

Derive the BinaryDecodable trait on this struct or enum, creating code to read the struct from an OPC-UA binary stream.

BinaryEncodable

Derive the BinaryEncodable trait on this struct or enum, creating code to write the struct to an OPC-UA binary stream.

Event

Derive the Event trait. This will also generate an implementation of the EventField trait.

EventField

Derive the EventField trait.

JsonDecodable

Derive the JsonDecodable trait on this struct or enum, creating code to read the struct from an OPC-UA stream with reversible encoding.

JsonEncodable

Derive the JsonEncodable trait on this struct or enum, creating code to write the struct to a JSON stream on OPC-UA reversible encoding.

UaEnum

Derive the UaEnum trait on this simple enum, creating code to convert it to and from OPC-UA string representation and its numeric representation. The enum must have a repr([int]) attribute.

UaNullable

Derive the UaNullable trait on this struct or enum. This indicates whether the value is null/default in OPC-UA encoding.

XmlDecodable

Derive the XmlDecodable trait on this struct or enum, creating code to read the struct from an OPC-UA xml stream.

XmlEncodable

Derive the XmlEncodable trait on this struct or enum, creating code to write the struct as OPC-UA XML.

XmlType

Derive the XmlType trait on this struct or enum. This simply exposes the type name, which can be overridden with an item-level opcua(rename = ...) attribute.
