Crate h3ron

This crate depends on the h3ron-h3-sys crate, which includes the C sources for libh3. So compiling requires a C toolchain and the cmake build tool.

Features

• use-serde: serde serialization/deserialization for most types of this crate.
• use-rayon
• roaring: Enables collections::H3Treemap based on the roaring crate.
• parse: Parse H3Cell from different string representations using H3Cell::from_str.

Traits

FromH3Index

trait for types which can be created from an H3Index

HasH3Resolution

trait to be implemented by all structs being based on H3 data with a given resolution

Index

Functions

compact_cells

the input vec must be deduplicated and all cells must be at the same resolution

Line of h3 indexes connecting two cells

grid_path_cells_size

Number of cells in a line connecting two cells

line

Generate h3 cells along the given linestring

max_grid_disk_size

maximum number of cells needed for the k_ring

res0_cell_count

res0_cell_count returns the number of resolution 0 indexes

res0_cells

provides all base cells in H3Index format
