22 * ShumateVectorReader:
23 *
24 * Provides low-level access to the contents of a vector tile.
25 *
26 * To create a new [class@VectorReader], use [ctor@VectorReader.new] and pass
27 * the bytes of a vector tile, which you might get from a [class@DataSource].
28 * Then, use [method@VectorReader.iterate] to get a [class@VectorReaderIter]
29 * and iterate over the features in the tile. You can create multiple
30 * [class@VectorReaderIter]s from the same [class@VectorReader].
31 *
32 * Since: 1.2
