Function distance 

Source 
pub fn distance(
    cch: &CchView<'_>,
    metric: &MetricView<'_>,
    source: u32,
    target: u32,
) -> u32
Expand description

Point-to-point shortest-path distance from source to target.

Returns INF_WEIGHT if target is unreachable, and 0 when source == target. Convenience wrapper over distance_matrix with a single source and target.

ยงPanics

Panics if source or target is >= node_count (same as distance_matrix).
