Base Vector Layer This is an intermediary for storing layer data in the Open Vector Tile format.

Fields

version: u8

the version of the vector tile. This is a number that tracks the OVT specification. and shouldn’t be tampered with

name: String

the name of the layer

extent: Extent

the extent of the vector tile (only 512, 1_024, 2_048, 4_096, and 8_192 are supported)

shape_defined: bool

if the shape was already passed in to the constructor

m_shape_defined: bool

if the M-Shape was already passed in to the constructor

shape: Shape

The shape used to describe the features properties in the layer

m_shape: Option<Shape>

the shape of each feature’s M-Values

features: Vec<BaseVectorFeature>

the features in the layer

Implementations

impl BaseVectorLayer

pub fn new( name: String, extent: Extent, features: Vec<BaseVectorFeature>, shape: Option<Shape>, m_shape: Option<Shape>, ) -> Self

Create a new BaseVectorLayer

pub fn add_feature(&mut self, feature: BaseVectorFeature)

Add a new feature to the layer

pub fn feature(&self, i: usize) -> &BaseVectorFeature

Get the feature at the given index

pub fn len(&self) -> usize

Get the number of features

pub fn is_empty(&self) -> bool

Check if the layer is empty
