Struct SlicerOne 

pub struct SlicerOne<V: Vertex = Coord<i32>, A = ()> { /* private fields */ }

Slices integer polylines into pieces for one fixed tile, accumulating only that tile.

The single-tile counterpart to SlicerAll: add_feature / add_feature_with work exactly the same, but each polyline is clipped only to this slicer’s tile. Because there is a single tile, the read API skips the tile level — iter_features yields the features directly.

Generic over the Vertex type V (defaults to Coord<i32>) and the per-feature attribute type A (defaults to ()); see SlicerAll for both axes.

Implementations

impl<V: Vertex, A> SlicerOne<V, A>

pub fn new(extent: u32, buffer: u16, tile: TileId) -> Result<Self, TileError>

Create a slicer bound to tile, with the given tile side / per-tile output resolution extent and buffer (see SlicerAll::new for the coordinate model).

Errors

• TileError::InvalidExtent if extent is 0 or greater than i32::MAX.
• TileError::BufferTooLarge if buffer is not strictly less than half the extent.

pub fn extent(&self) -> u32

The tile side / per-tile output resolution: kept vertices land in 0..extent.

pub fn buffer(&self) -> u16

The buffer kept around every tile, in tile-space units.

pub fn tile(&self) -> TileId

The tile this slicer clips into.

pub fn add_feature_with<P: AsRef<[V]>>( &mut self, polyline: P, attr: A, ) -> Result<&mut Self, TileError>

Add polyline as an independent feature carrying attr, clipped to this slicer’s tile. Chainable. The feature (and its attribute) is recorded only if something of polyline lands in the tile; otherwise attr is dropped. Reach it back through FeatureView::attr.

When A = (), prefer add_feature.

Atomic: the polyline is fully sliced first, so on error the accumulator is left unchanged.

Errors

TileError::Overflow if the tile’s box or a kept vertex overflows i32.

pub fn iter_features(&self) -> impl Iterator<Item = FeatureView<'_, V, A>>

Iterate this tile’s features, in the order they were first added. Each FeatureView exposes that feature’s clipped polylines and its attr.

pub fn len(&self) -> usize

Number of features accumulated for the tile.

pub fn is_empty(&self) -> bool

Whether nothing has been accumulated yet.

pub fn clear(&mut self)

Discard everything accumulated so far, keeping the extent/buffer/tile config.

impl<V: Vertex> SlicerOne<V, ()>

pub fn add_feature<P: AsRef<[V]>>( &mut self, polyline: P, ) -> Result<&mut Self, TileError>

Add polyline as an independent feature with no attribute — shorthand for add_feature_with(polyline, ()). Available only when A = ().

Errors

TileError::Overflow if the tile’s box or a kept vertex overflows i32.
