K-mers and associated operations.
This library provides functionality for extracting k-mers from sequences,
and manipulating them in useful ways. The underlying representation is
64-bit integers (u64), so k > 32 is not supported by this library.
K-mers (or q-grams in some computer science contexts) are k-length sequences of DNA/RNA "letters" represented as unsigned integers. Following usual practice,
- "A" -> b00
- "C" -> b01
- "G" -> b10
- "T" or "U" -> b11
which has the nice property that the complementary bases are bitwise complements.
