pub fn is_susceptible_rrl_by_snp_calls_rare(
pos_opt: Option<&RrlPosition2058_2059>,
snp_calls: &[RrlSnpCall],
) -> Option<bool>Expand description
Returns Some(false) only when position 2058/2059 is wildtype (Some(true)) and a
resistance-conferring SNP alt is observed elsewhere; otherwise returns None.
This captures rare mutations where resistance is not due to 2058/2059.
