Struct 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.

Implementations

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.

Trait Implementations

impl Clone for Layer

fn clone(&self) -> Layer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Layer

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for Layer

fn from(name: &str) -> Layer

Converts to this type from the input type.

impl From<String> for Layer

fn from(name: String) -> Layer

Converts to this type from the input type.

impl PartialEq for Layer

fn eq(&self, other: &Layer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
