Struct h3ron::iter::H3DirectedEdgesBuilder

pub struct H3DirectedEdgesBuilder { /* private fields */ }

Creates H3DirectedEdge from cells while only requiring a single memory allocation when the struct is created.

Implementations

impl H3DirectedEdgesBuilder

pub fn new() -> Self

pub fn from_origin_cell( &mut self, cell: &H3Cell ) -> Result<UncheckedIter<'_, H3DirectedEdge>, Error>

Create an iterator for iterating over all H3DirectedEdge leading away from the given H3Cell.

pub fn previous_edges_leading_to_origin( &mut self, edge: &H3DirectedEdge ) -> Result<EdgeIter<'_>, Error>

get an iterator over all edges leading to the origin of the input edge except the reverse of input

pub fn following_edges_leading_from_destination( &mut self, edge: &H3DirectedEdge ) -> Result<EdgeIter<'_>, Error>

get all following edges leading away from the destination of the input edge, except the reverse of the input.
