Struct MapTileCache 

pub struct MapTileCache { /* private fields */ }

a cache for map tiles on the local filesystem

Implementations

impl MapTileCache

pub fn new(cache_directory: PathBuf, ratelimiter: Option<Ratelimiter>) -> Self

creates a new MapTileCache

pub async fn get_map_tile( &mut self, map_tile_descriptor: &MapTileDescriptor, ) -> Result<Option<MapTile>, MapTileCacheError>

fetches a map tile from the Second Life main map servers or the local cache

Errors

returns an error if the HTTP request fails of if the result fails to be parsed as an image

pub async fn does_map_tile_exist( &mut self, map_tile_descriptor: &MapTileDescriptor, ) -> Result<bool, MapTileCacheError>

figures out if a map tile exist by checking the local in-memory and disk caches or fetching the map tile from the server

Errors

returns an error if fetching the map tile from cache or remotely fails

pub async fn does_region_exist( &mut self, grid_coordinates: &GridCoordinates, ) -> Result<bool, MapTileCacheError>

figures out if a region exists based on the existence of map tiles for it, starting with the lowest zoom level and potentially going up to the highest one if all the other zoom levels have a tile for that region

Errors

returns an error if fetching map tiles from cache or remotely fails

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