pub fn is_susceptible_rrl(
pos_opt: Option<&RrlPosition2058_2059>,
snp_calls: &[RrlSnpCall],
) -> Option<bool>Expand description
Returns Some(true) for wildtype (susceptible), Some(false) for a resistance-conferring
mutation, and None when the call is undetermined.
If any snp_calls entry shows a resistance-conferring alt base, returns Some(false)
regardless of pos_opt. Otherwise delegates to the position-based call.
pos_opt: None (anchor not found) still allows SNP calls to return Some(false).
