Crate marc

Library to work with the MARC 21 Format for Bibliographic Data

Examples

Reading

let input = fs::File::open("test/fixtures/3records.mrc")?;
let mut count = 0;

for (i, record) in Records::new(input).enumerate() {
    let record = dbg!(record?);
    match i {
        0 => assert_eq!(record.field(b"001")[0].get_data::<str>(), "000000002"),
        1 => assert_eq!(record.field(b"001")[0].get_data::<str>(), "000000005"),
        2 => assert_eq!(record.field(b"001")[0].get_data::<str>(), "000000009"),
        _ => panic!(),
    }
    count += 1;
}

assert_eq!(count, 3);

Creating

let mut builder = RecordBuilder::new();
let record = builder
    .add_fields(fields!(
        control fields: [
            b"001" => "000000002",
            b"003" => "RuMoRGB",
        ];
        data fields: [
            b"979", b"  ", [
                b'a' => "autoref",
                b'a' => "dlopen",
            ],
        ];
    ))?
    .get_record()?;
assert_eq!(record.as_ref(), b"00100nam  2200061 i 4500001001000000003000800010\
    979002000018\x1E000000002\x1ERuMoRGB\x1E  \x1Faautoref\x1Fadlopen\x1E\x1D");

Updating

let input = fs::File::open("test/fixtures/3records.mrc")?;
let orig_record = Records::new(input).next().expect("should be here")?;
let mut builder = RecordBuilder::from_record(&orig_record);
let record = builder
    // we'll replace `001`
    .filter_fields(|f| f.get_tag() != "001")
    .add_field((b"001", "foo"))?
    // we'll remove `979a` with value `dlopen` (note that an empty `979` will remain)
    .filter_subfields(|_, sf| sf.get_tag() != "979" ||
        sf.get_identifier() != 'a' ||
        sf.get_data::<str>() != "dlopen")
    .get_record()?;

assert_eq!(record.as_ref(), "01339nam a2200301 i 45000010004000000030008000040050017000120080\
