Modules

charset

Character set conversion between EBCDIC codepages and UTF-8. Character set conversion utilities

determinism

Determinism validation for decode, encode, and round-trip operations. Determinism validation for COBOL copybook encoding and decoding operations.

edited_pic

Edited PIC (numeric editing) decode and encode support. Edited PIC (Phase E2 + E3) decode and encode support

file

Schema-aware file framing integration. Schema-aware file processing integration.

iterator

Streaming record iterator for file-level decoding. Record iterator for streaming access to decoded records

lib_api

Core library API: record decode/encode and file-level processing. Core decode / encode API for COBOL binary data.

numeric

Numeric field decoding and encoding (zoned decimal, packed decimal, binary).

options

Configuration types: codepage, record format, JSON modes, raw capture. Configuration option types owned by the codec runtime.

Enums

Codepage

UnmappablePolicy

Policy for handling unmappable characters during codepage conversion. Policy for handling characters that have no mapping.

Constants

JSON_SCHEMA_VERSION

Stable JSONL schema identifier for decoder output.
