nanoxml

A truly minimal XML (de)serializer for Rust.

Features

• serialization and deserialization of very basic XML (only attributes and elements are supported)
• derive for (de)serialization of structs and enums (optional)
• tiny codebase (~400 LoC + optional ~900 LoC for derive)
• no runtime dependencies
• no_std
• optional alloc support
• optional heapless support
• UTF-8 only

Derive Attributes

• #[nanoxml(attr)]: (de)serialize as attribute (i.e. key="value")
• #[nanoxml(text)]: (de)serialize as text (i.e. content between <tag></tag> without an additional sub-element for the field)
• #[nanoxml(rename = "xmlname")]: use xmlname as the attribute key or tag name in the XML
• #[nanoxml(seq)]: must be specified for "sequence" fields (e.g. Vec or array)
• #[nanoxml(skip_ser)]: skip this field when serializing to XML
• #[nanoxml(default_de)]: when this field is not present when deserializing the XML, fall back to the Default::default() value
• #[nanoxml(default_de = "func")]: when this field is not present when deserializing the XML, call func to get a fallback value
