Parsed TileJSON metadata.

This is a framework-agnostic representation of the subset of TileJSON fields that the engine needs to configure tile managers and sources.

Fields

tilejson: String

TileJSON spec version (e.g. "3.0.0").

name: Option<String>

Optional human-readable name.

description: Option<String>

Optional description.

version: Option<String>

TileJSON version string (semver).

attribution: Option<String>

Optional attribution HTML string.

tiles: Vec<String>

Tile URL templates with {z}, {x}, {y} placeholders.

min_zoom: u8

Minimum zoom level supported by the source.

max_zoom: u8

Maximum zoom level supported by the source.

bounds: Option<[f64; 4]>

Geographic bounds as [west, south, east, north] in WGS-84 degrees.

None means the source covers the whole world.

center: Option<[f64; 3]>

Default center + zoom as [lon, lat, zoom].

scheme: TileScheme

Tile encoding scheme.

vector_layers: Vec<VectorLayerMeta>

Vector layer metadata (only present for vector tile sources).

Implementations

impl TileJson

pub fn with_tiles(tiles: Vec<String>) -> Self

Create a minimal TileJSON with a single tile URL template.

pub fn first_tile_url(&self) -> Option<&str>

Return the first tile URL template, if any.

pub fn is_vector(&self) -> bool

Return true if this TileJSON describes a vector tile source (has vector_layers).

pub fn source_layer_names(&self) -> Vec<&str>

Return the names of all declared vector source layers.

pub fn contains_point(&self, lon: f64, lat: f64) -> bool

Check whether a geographic coordinate is within the source bounds.

Returns true when no bounds are set (unbounded source).

Trait Implementations

impl Clone for TileJson

fn clone(&self) -> TileJson

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TileJson

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

Formats the value using the given formatter.

impl Default for TileJson

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TileJson

fn eq(&self, other: &TileJson) -> 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.
