marc-record

A Rust library for parsing MARC records, specifically using the MARC21 format, with either UTF-8 or MARC-8 encoding. This library has been tested on a bunch of records from a single provider and various samples found in the wild. Since MARC is an open standard with many variations, we may not support all the files. In particular, we do not support MARCXML at the moment.

Getting started

Add the crate to your rust library:

cargo add marc-record

Load, parse and inspect a record:

use std::fs::File;
use std::io::Read;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut contents = Vec::new();
    File::open("./record.mrc")?.read_to_end(&mut contents)?;
    let records = marc_record::parse_records(&contents)?;
    println!("File contains {} records", records.len());
    let record1 = &records[0];
    for field in record1.fields.iter() {
        println!("Field: {:?}", field);
    }
    Ok(())
}
