copybook-record-io

Record-format dispatch for copybook-rs.

Overview

Provides a format-agnostic API for single-record I/O that dispatches to either fixed-length (LRECL) or RDW (variable-length) framing. This crate bridges the dedicated framing microcrates (copybook-fixed, copybook-rdw) behind a unified read_record / write_record interface.

Usage

use copybook_record_io::{read_record, write_record};
use copybook_options::RecordFormat;
use std::io::Cursor;

// Write a fixed-length record
let mut output = Vec::new();
write_record(&mut output, b"DATA", RecordFormat::Fixed).unwrap();

// Read it back
let mut input = Cursor::new(&output);
let record = read_record(&mut input, RecordFormat::Fixed, Some(4)).unwrap();
assert_eq!(record.unwrap(), b"DATA");

Public API

• read_record / write_record — Format-agnostic single-record I/O
• Re-exports: FixedRecordReader, FixedRecordWriter, RDWRecord, RDWRecordReader, RDWRecordWriter
