pub struct TileRepository {
    tree: BTreeMap<Quadkey, StoredTile>,
}

Stores and provides access to a quad tree of cached tiles with world tile coords.

Fields

tree: BTreeMap<Quadkey, StoredTile>

Implementations

impl TileRepository

pub fn new() -> Self

pub fn put_tessellated_layer(&mut self, layer: StoredLayer)

Inserts a tessellated layer into the quad tree at its world tile coords. If the space is vacant, the tessellated layer is inserted into a new [crate::io::tile_repository::CachedTile]. If the space is occupied, the tessellated layer is added to the current [crate::io::tile_repository::CachedTile].

pub fn iter_tessellated_layers_at(
    &self,
    coords: &WorldTileCoords
) -> Option<impl Iterator<Item = &StoredLayer> + '_>

Returns the list of tessellated layers at the given world tile coords. None if tile is missing from the cache.

pub fn retain_missing_layer_names(
    &self,
    coords: &WorldTileCoords,
    layers: &mut HashSet<String>
)

Removes all the cached tessellate layers that are not contained within the given layers hashset.

pub fn is_layers_missing(
    &self,
    coords: &WorldTileCoords,
    layers: &HashSet<String>
) -> bool

Checks if a layer is missing from the given layers set at the given coords.
