ebcdic-rs

Provides methods to convert ebcsic to ascii format and back

EBCDIC to ASCII

It support EBCDIC format (character set IBM-1047) which is used in IBM's TPF and OS/390 operating systems. It additionally provides flags to replace non-printable ascii characters with space characters and also replace NEL (0x15) with '\n' characters.

ASCII to EBCDIC

It converts US-ASCII to EBCDIC format (character set IBM-1047) . It additionally provides flags to replace '\n' character with NEL (0x15).

Code example

extern crate ebcdic;
use std::str;
use ebcdic::Ebcdic;

fn main() {
    /// ascii string
    let ascii_str = "       IDENTIFICATION DIVISION.                                         00000010";
    let mut ebcdic_bytes: [u8; 80] = [0; 80];
    //convert ascii to ebcdic with replace '\n' with 0x15 flag set to true
    Ebcdic::ascii_to_ebcdic(ascii_str.as_bytes(), &mut ebcdic_bytes, 80, true);
    
    let mut ascii_str_2: [u8; 80] = [0; 80];
    // convert ebcdic to ascii with replace 0x15 with '\n' set to true
    Ebcdic::ebcdic_to_ascii(&ebcdic_bytes, &mut ascii_str_2, 80, false, true);
    assert_eq!(ascii_str, str::from_utf8(&ascii_str_2).unwrap());
    
    
    let ebcdic_bytes: [u8; 20] = [
           0xe2,0x4b,0x40,0xc4,0x4b,
           0x40,0xc2,0xd6,0xd9,0xd4,
           0xc1,0xd5,0x40,0x40,0x40,
           0x40,0x40,0x40,0x40,0x40,
       ];
    let ascii = String::from("S. D. BORMAN        ");
    let mut ascii_str: [u8; 20] = [0u8; 20];
    Ebcdic::ebcdic_to_ascii(&ebcdic_bytes, &mut ascii_str, 20, false, true);
    println!("Ascii Output:{}", str::from_utf8(&ascii_str).unwrap());
    assert_eq!(ascii.as_bytes(), ascii_str);
