Mapbox specification for a Layer

Fields

version: u16

the version of the vector tile layer.

Implementations

impl MapboxVectorLayer

pub fn new(pbf: Rc<RefCell<Protobuf>>, is_s2: bool) -> MapboxVectorLayer

Create a new MapboxVectorLayer

Trait Implementations

impl Debug for MapboxVectorLayer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&mut MapboxVectorLayer> for BaseVectorLayer

fn from(mvt: &mut MapboxVectorLayer) -> Self

Converts to this type from the input type.

impl ProtoRead for MapboxVectorLayer

fn read(&mut self, tag: u64, pb: &mut Protobuf)

The read method is used to read a field from a protobuf message. The tag parameter is used to determine which field to read into the struct. The pbf parameter is used to read the data in the appropriate format.

impl VectorLayerMethods for MapboxVectorLayer

fn len(&self) -> usize

the number of features in the layer

fn is_empty(&self) -> bool

Check if the layer is empty

fn version(&self) -> u16

the version of the vector tile layer.

fn name(&self) -> String

the name of the layer

fn extent(&self) -> usize

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

fn feature(&mut self, i: usize) -> Option<&mut dyn VectorFeatureMethods>

grab a feature from the layer
