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
  Trait to handle types having a H3 Index like cells and edges

Functions

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

  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
