Struct MapTileOptions 

pub struct MapTileOptions {
    pub prefetch_zoom_delta: Option<u32>,
    pub lod_min_radius: Option<f64>,
    pub lod_scale: Option<f64>,
    pub lod_pitch_threshold: Option<f64>,
    pub lod_zoom_shift: Option<f64>,
    pub lod_mode: Option<TileLodMode>,
}

How the map picks the tiles to load.

The lod_ members lower the level of detail away from the camera, so the map loads fewer tiles when the pitch is high.

See mln_map_tile_options in the C API reference.

Fields

prefetch_zoom_delta: Option<u32>

How many zoom levels lower the map also loads tiles for, so it can show a coarse map while the current tiles load. 0 loads only the current tiles.

lod_min_radius: Option<f64>

The radius around the view point, in tiles, that keeps full detail.

lod_scale: Option<f64>

Scales the distance to the view point. Above 1 lowers the detail.

lod_pitch_threshold: Option<f64>

The pitch, in degrees, above which the map lowers the detail.

lod_zoom_shift: Option<f64>

Zoom levels to add for picking the detail. Below 0 loads fewer tiles.

lod_mode: Option<TileLodMode>

TileLodMode::Distance ignores lod_min_radius.
