pub fn reverse_complement(seq: &[u8]) -> Vec<u8> āExpand description
Reverse-complement a DNA sequence (mirrors io.c::sreverse).
C also flips TāU when the input had more U than T (treats it as
RNA), but the adjustdirection caller has already gappicked and
case-preserved its input via mafft-io, and we keep the original
alphabet to stay byte-identical with Cās setdirection output.
