Struct mapbox_vector_tile::Layer

pub struct Layer {
    pub name: String,
    pub features: Vec<Feature>,
    pub extent: u32,
}

A Layer in a vector tile

Fields

name: String

The layer's name

features: Vec<Feature>

The features in this layer

extent: u32

The "extent" of this layer. Usualyy 4096 is used.

Methods

impl Layer

pub fn new<S: Into<String>>(name: S) -> Self

Create an empty layer with this name (and 4096 extent)

pub fn new_and_extent(name: String, extent: u32) -> Self

Construct layer with this name and extent

pub fn set_locations(&mut self, geometry_tile: &Tile)

Move all the geometries in this layer so that it's at this geometry_tile.

pub fn add_feature(&mut self, f: Feature)

Add a feature to this layer.

pub fn is_empty(&self) -> bool

True iff this layer has no features

pub fn write_to<W: Write>(self, writer: &mut W)

Encode this layer to the writer.

pub fn to_bytes(self) -> Vec<u8>

Encode this layer into bytes.
