Struct RasterSource 

pub struct RasterSource {
    pub url: String,
    pub max_zoom: Option<u8>,
    pub neighbor_fetch: bool,
    pub on_missing: OnMissing,
    pub attribution: Option<String>,
}

RGBA raster tile pyramid (satellite imagery, pre-rendered basemaps, …) consumed by the raster node as a canvas-sized Raster. The host fetches the 3×3 neighbourhood per render and stitches it onto the padded canvas, so downstream filters see seamless pixels across tile borders.

Fields

url: String

XYZ URL template with {z}, {x}, {y} placeholders, a TileJSON document URL (anything ending in .json), or a PMTiles archive (anything ending in .pmtiles; local path or http(s):// URL). PNG / WebP / JPEG tiles are sniffed from content.

max_zoom: Option<u8>

Highest zoom available from the source. Requests above this zoom upsample from the ancestor at max-zoom.

neighbor_fetch: bool

Fetch the 8 neighbouring tiles and stitch them so the pad region has real pixels.

on_missing: OnMissing

What a 404 within the zoom range means — transparent pixels, upsample from a parent, or fail the render.

attribution: Option<String>

Explicit attribution. When absent, hosts inherit upstream metadata (TileJSON attribution / PMTiles metadata).
