NamedCsvReader should have support for returning default value if field is not present about fastcsv HOT 3 CLOSED

Thank you for bringing this up!

Just added this functionality by 5ebb7d5. This allows something like this:

try (var csv = NamedCsvReader.builder().build("col1,col2\nfoo").stream()) {
    csv.forEach(rec -> {
        var col1 = rec.findField("col1").orElse("default");
        var col2 = rec.findField("col2").orElse("default");
        System.out.printf("col1: %s, col2: %s%n", col1, col2);
    });
}

Will be part of version 3 which will be released within the next few months.

Thanks for update, actually later I realised that I can instead use csvRow.getFields() which gives a map and then I can check containsKey

I was about to close the issue.

Go ahead and use it, if it fits your need. As that methods requires another "bigger" object (Map) being built for every record, I'm happy to also offer a more elegant and less resource consuming way to access optional fields.
