Example

Iterate though a complete FASTX file and a filtered FASTX file, synchronizing on records present in both:

with (
    FastxFile(in_source) as source,
    FastxFile(in_subseq) as subseq,
):
    for count, (fq, fq_subseq) in enumerate(
        sync(
            iter1=source,
            iter2=subseq,
            key1=lambda rec: rec.name,
            key2=lambda rec: rec.name,
            cmp_func=lambda x, y: (x == y) - 1,  # only advance iter1 when non-equal
        ),
        start=1,
    ):
        assert fq.name == fq_subseq.name, f"Names for record {count} should be equal!"
