pub fn is_susceptible_rrs_by_snp_calls_rare(
snp_calls: &[RrsSnpCall],
) -> Option<bool>Expand description
Returns Some(false) if any observed SNP base is a resistance-conferring alt, or None
otherwise. Parallel to is_susceptible_rrl_by_snp_calls_rare: rrs has no position-based
anchor call, so all SNP resistance here is inherently not explained by a position mutation.
