Expand description

“Differential” routing calculates the shortest path from (multiple) origin cells to the N nearest destinations. This done once to the un-modified graph, and once the the graph with a set of nodes being removed, the exclude_cells parameter.

Required Methods§

Source

fn differential_shortest_path_map<I, OPT, PM, O>( &self, origin_cells: I, destination_cells: I, exclude_cells: &H3Treemap<H3Cell>, options: &OPT, path_transform_fn: PM, ) -> Result<HashMap<H3Cell, ExclusionDiff<O>>, Error>
where I: IntoIterator, I::Item: Borrow<H3Cell>, OPT: ShortestPathOptions + Send + Sync, O: Send + Ord + Clone, PM: Fn(Path<W>) -> Result<O, Error> + Send + Sync,

Provided Methods§

Source

fn differential_shortest_path<I, OPT>( &self, origin_cells: I, destination_cells: I, exclude_cells: &H3Treemap<H3Cell>, options: &OPT, ) -> Result<HashMap<H3Cell, ExclusionDiff<Path<W>>>, Error>
where I: IntoIterator, I::Item: Borrow<H3Cell>, OPT: ShortestPathOptions + Send + Sync,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
