# obikmer

`obikmer` is a Rust tool for manipulation, counting, indexing, and set operations on DNA sequences represented as kmer sets.

## Constraints

- Target scale: individual genome datasets, tens of Gbases
- Maximum efficiency in computation, memory, and disk usage
- Input formats: FASTA, FASTQ, gzip, streaming stdin

## Priority operations

- Kmer counting (frequencies)
- Fast search / query
- Set operations: union, intersection, difference
