Struct h3ron::collections::indexvec::IndexVec

pub struct IndexVec<T: FromH3Index + Index> { /* private fields */ }

A H3Index-Vec intended to interface between libh3 by providing continuous memory to place h3indexes in.

Provides iterators to create Index implementing types from the primitive H3Index/u64 types. The iterators automatically skip all 0 values (as created some libh3 functions).

The struct does not provide a len() method as this would create the impression that accessing this method is cheap. As a count of the contained elements requires checking each for 0, that functionality is provided by IndexVec::count()
