Struct RasterTile 

pub struct RasterTile {
    pub x: u32,
    pub y: u32,
    pub zoom: u8,
    pub data: Vec<u8>,
}

A single raster tile at a specific zoom level and tile coordinate.

Follows the XYZ / WMTS slippy-map convention used by web mapping libraries (Leaflet, MapLibre, OpenLayers, etc.).

Fields

x: u32

Tile column index (0 … 2^zoom − 1, left to right)

y: u32

Tile row index (0 … 2^zoom − 1, top to bottom)

zoom: u8

Zoom level (0 = world overview, higher = more detail)

data: Vec<u8>

Raw tile image bytes (PNG, JPEG, WebP, etc.)

Implementations

impl RasterTile

pub fn tiles_per_axis(zoom: u8) -> u32

Return the number of tiles per axis at this zoom level: 2^zoom.

Saturates at u32::MAX for zoom ≥ 32 (which is never useful in practice, but avoids overflow).

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

Return the normalised bounding box (min_x, min_y, max_x, max_y) for this tile, where coordinates are in the range [0.0, 1.0].

Useful for converting to geographic coordinates when combined with the dataset’s crate::DatasetInfo::geotransform.

pub fn has_data(&self) -> bool

Return true if the tile data is non-empty.
