copybook-codepage

Codepage domain types and helpers for copybook-rs.

This crate provides:

• Codepage enum for ASCII and supported EBCDIC variants
• UnmappablePolicy enum for decode/encode fallback behavior
• space_byte for codepage-specific space byte selection
• get_zoned_sign_table for zoned decimal sign semantics

Usage

use copybook_codepage::{Codepage, UnmappablePolicy, get_zoned_sign_table, space_byte};

assert_eq!(space_byte(Codepage::ASCII), 0x20);
assert_eq!(space_byte(Codepage::CP037), 0x40);

let table = get_zoned_sign_table(Codepage::CP037);
assert_eq!(table[0xC], (true, false));

let policy = "replace".parse::<UnmappablePolicy>().unwrap();
assert_eq!(policy, UnmappablePolicy::Replace);
