Implementations

impl Tile

pub fn new(x: u32, y: u32, z: u32) -> Self

pub fn set_extension(&mut self, ext: &str) -> Result<(), MapEngineError>

pub fn to_tuple(&self) -> (u32, u32, u32)

pub fn ul(&self) -> (f64, f64)

Return the coordinates (lat, long) of the upper-left tile corner

pub fn ul_xy(&self) -> (f64, f64)

Return the coordinates (mercator x, y) of the upper-left tile corner

pub fn bounds(&self) -> (f64, f64, f64, f64)

Return the bounds (lat, lng) of the tile

The order of the output is (min_lng_deg, max_lat_deg, max_lng_deg, min_lat_deg)

pub fn bounds_xy(&self) -> (f64, f64, f64, f64)

Return the bounds (mercator x, y) of the tile

The order of the output is (min_lng_deg, max_lat_deg, max_lng_deg, min_lat_deg)

pub fn vertices(&self) -> [(f64, f64); 4]

Return the vertices of the tile

The order of the vertices is: upper-left, lower-left, lower-right and upper-right

pub fn zoom_out(&self, zoom: Option<u32>) -> Option<Self>

Return a tile from a lower zoom level that contains this tile

pub fn zoom_in(&self, zoom: Option<u32>) -> Option<Vec<Self>>

Return the tiles from a higher zoom level contained by this tile

pub fn from_lat_lng(lng: f64, lat: f64, zoom: u32) -> Self

Find the Tile intersecting the coordinate at a given zoom level

pub fn to_window( &self, raster: &Raster, ) -> Result<(Window, bool), MapEngineError>

Transform a Tile to a Window.

Arguments

• raster - Raster used for the conversion.

Trait Implementations

impl Debug for Tile

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

Formats the value using the given formatter.

impl PartialEq for Tile

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