pub fn num_localities(&self) -> u64

Get number of system localities (NUMA nodes)

pub fn distance(&self, from: u64, to: u64) -> u8

Get distance between two localities Returns 255 if indices are out of bounds

pub fn locality_distances(&self, from: u64) -> Option<&[u8]>

Get all distances for a locality
