copybook-options

Configuration primitives for copybook codec behavior.

Overview

Defines the DecodeOptions and EncodeOptions structs that control record format, codepage, JSON number mode, raw capture, zoned encoding preferences, and float format. These option types are the shared configuration surface used by the codec and CLI layers.

Usage

use copybook_options::{DecodeOptions, RecordFormat, JsonNumberMode, Codepage};

let options = DecodeOptions::new()
    .with_format(RecordFormat::Fixed)
    .with_codepage(Codepage::CP037)
    .with_json_number_mode(JsonNumberMode::Lossless)
    .with_threads(4);

Public API

DecodeOptions / EncodeOptions — Builder-pattern configuration structs
RecordFormat — Fixed or RDW
JsonNumberMode — Lossless or Native
RawMode — Off, Record, Field, RecordRDW
FloatFormat — IeeeBigEndian or IbmHex
Codepage / UnmappablePolicy / ZonedEncodingFormat — Re-exported charset types

RawMode variants

Variant	Description
`Off`	No raw payload captured (default)
`Record`	Capture record payload bytes in `__raw_b64`
`RecordRDW`	Capture RDW header + payload bytes in `__raw_b64`
`Field`	Capture per-field raw values in `<FIELD_NAME>__raw_b64`
