Struct Metric 

pub struct Metric {
    pub forward: Vec<u32>,
    pub backward: Vec<u32>,
}

A customized metric: the forward + backward shortcut weights of every CCH arc. Field semantics match the persisted .cch-metric sections and crate::bundle::MetricView.

Fields

forward: Vec<u32>

forward[arc] → shortcut weight in the up→down direction. Length = cch_arc_count. INF_WEIGHT marks an unreachable arc.

backward: Vec<u32>

backward[arc] → shortcut weight in the down→up direction. Length = cch_arc_count.

Implementations

impl Metric

pub fn view(&self) -> MetricView<'_>

Borrow this in-memory metric as a MetricView — the query-ready view consumed by distance_matrix and node_path.

impl Metric

pub fn save(&self, path: &Path) -> Result<()>

Writes this customized metric to path in the CCH_METR v1 format, byte-identical to RoutingKit’s cch_save_metric.

Errors

Returns io::Error on any I/O failure.
