Struct CCHQueryResult 

pub struct CCHQueryResult<'b, 'a> { /* private fields */ }

The result of a single execution of a CCHQuery. Holds a mutable reference to the query to ensure it is not reset or reused while the result is still alive. So you need to drop the result before reusing the query. When the result is dropped, the query is automatically reset.

Implementations

impl<'b, 'a> CCHQueryResult<'b, 'a>

pub fn distance(&self) -> Option<u32>

Return the shortest path distance result of CCHQuery::run. Returns None if no target is reachable.

pub fn node_path(&self) -> Vec<u32>

Reconstruct and return the node id sequence of the current best path. Returns empty vec if no target is reachable.

pub fn arc_path(&self) -> Vec<u32>

Reconstruct and return the original arc ids along the shortest path. Returns empty vec if no target is reachable.
