Struct FeatureView 

pub struct FeatureView<'a, V: Vertex, A = ()> { /* private fields */ }

A borrowed view of one feature’s clipped polylines within a tile, yielded by TileView::iter_features / SlicerOne::iter_features.

Implementations

impl<'a, V: Vertex, A> FeatureView<'a, V, A>

pub fn attr(&self) -> &'a A

This feature’s per-feature attribute in this tile — the value passed to add_feature_with, duplicated onto every tile the feature touches. With the default A = () this is a reference to the unit value.

pub fn iter_polylines(&self) -> impl Iterator<Item = &'a [V]> + use<'a, V, A>

Iterate this feature’s polylines (runs) in this tile, each a vertex slice in the tile’s local frame. A feature yields several polylines where the input left the tile and re-entered.
