S2 TileJSON V1.0.0

let meta: Metadata =
  serde_json::from_str(meta_str).unwrap_or_else(|e| panic!("ERROR: {e}"));

Represents a TileJSON metadata object for the new S2 spec.

If you’re unsure of which spec you’re using, use the UnknownMetadata type.

S2TileJSON Spec

Fields

s2tilejson: String

The version of the s2-tilejson spec. Matches the pattern: ^\d+\.\d+\.\d+\w?[\w\d]*$.

version: String

The version of the data. Matches the pattern: ^\d+\.\d+\.\d+\w?[\w\d]*$.

name: String

The name of the data

scheme: Scheme

The scheme of the data

description: String

The description of the data

type: SourceType

The type of the data

extension: String

The extension to use when requesting a tile

encoding: Encoding

The encoding of the data

faces: Vec<Face>

List of faces that have data

bounds: LonLatBounds

Bounding box array [west, south, east, north].

wmbounds: WMBounds

WM Tile fetching bounds. Helpful to not make unecessary requests for tiles we know don’t exist

s2bounds: FaceBounds

S2 Tile fetching bounds. Helpful to not make unecessary requests for tiles we know don’t exist

minzoom: u8

minzoom at which to request tiles. [default=0]

maxzoom: u8

maxzoom at which to request tiles. [default=27]

centerpoint: Center

The center of the data

attributions: Attributions

{ [‘human readable string’]: ‘href’ }

layers: LayersMetaData

Track layer metadata

tilestats: TileStatsMetadata

Track tile stats for each face and total overall

vector_layers: Vec<VectorLayer>

Old spec but required for functional compatibility, track basic layer metadata

tilejson: Option<String>

Version of the TileJSON spec used. Matches the pattern: ^\d+\.\d+\.\d+\w?[\w\d]*$.

tiles: Option<Vec<String>>

Array of tile URL templates.

attribution: Option<String>

Attribution string.

fillzoom: Option<u8>

Fill zoom level. Must be between 0 and 30.

center: Option<[f64; 3]>

Center coordinate array [longitude, latitude, zoom].

data: Option<Vec<String>>

Array of data source URLs.

grids: Option<Vec<String>>

Array of UTFGrid URL templates.

legend: Option<String>

Legend of the tileset.

template: Option<String>

Template for interactivity.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metadata

where Metadata: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Metadata

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

impl Serialize for Metadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
