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

Required Methods

fn h3index(&self) -> H3Index

Get the u64 H3 Index address

fn new(h3index: H3Index) -> Self

create an index from the given u64.

No validation is performed.

fn validate(&self) -> Result<(), Error>

Checks the validity of the index

Provided Methods

fn resolution(&self) -> u8

Gets the index resolution (0-15)

fn is_valid(&self) -> bool

Checks the validity of the index

fn direction(&self) -> H3Direction

Retrieves the direction of the current index

Panics

May panic if self is invalid or has a resolution of 0

fn direction_checked(&self) -> Result<H3Direction, Error>

Retrieves the direction of the current index

Errors

May fail if self is invalid or has a resolution of 0

fn direction_to_parent_resolution(
    &self,
    target_resolution: u8
) -> Result<H3Direction, Error>

Retrieves the direction of the current index relative to a parent at target_resolution
