Crate kobold_xml 

kobold-xml

A clean-room, Rust-native COBOL-data XML layer. It turns a decoded COBOL record (a tree of named fields with values) into deterministic XML, and is independent of GnuCOBOL/libcob – it links no COBOL runtime and reproduces no runtime’s exact bytes.

Not a GnuCOBOL parity claim. This is a forward-looking interchange layer: what a safe Rust-native COBOL XML layer should do, not what GnuCOBOL 3.2 does. Its evidence is the EXT.XML.* court namespace.

v0.1 – XML GENERATE

use kobold_xml::{CobolField, record_to_xml, generate, GenerateOptions};

let rec = CobolField::group("ACCOUNT", vec![
    CobolField::alnum("NAME", &b"JANE     "[..]),
    CobolField::numeric("BALANCE", &b"104277"[..], 2, false), // 1042.77
]);
let xml = generate(&record_to_xml(&rec), &GenerateOptions::default());
assert_eq!(xml, "<ACCOUNT><NAME>JANE</NAME><BALANCE>1042.77</BALANCE></ACCOUNT>");

• [generate] serializes an explicit XmlElement tree to deterministic XML (EXT.XML.GENERATE.1), with explicit text/attribute escaping (EXT.XML.ESCAPE.1).
• record_to_xml maps a CobolField record tree to that XML tree (FILLER omitted; v0.1 value policy documented on the cobol module).

v0.2 (planned) – XML PARSE

A real event stream + generate->parse round-trip (EXT.XML.PARSE.1 / EXT.XML.ROUNDTRIP.1).

Modules

cobol

A clean-room COBOL-record data model and its XML rendering. This is independent of GnuCOBOL/libcob – it is a plain Rust description of a record (a tree of named fields with decoded values) and a deterministic mapping to the [crate::generate] XML element tree. The caller decodes their COBOL data into CobolFields by whatever means they like; kobold-xml does not link any COBOL runtime.

generate

XML GENERATE – a deterministic serializer of an explicit element tree to XML text.

Constants

COURT_NAMESPACE

The extension court namespace – never GNURUST.*. So a reader can never mistake this crate’s evidence for a GnuCOBOL parity claim.
