Struct StandardTileProvider 

pub struct StandardTileProvider { /* private fields */ }

Standard tile provider with caching.

fetch_tile routes on the configured TileSource:

• TileSource::Http delegates to the supplied TileProtocol.
• TileSource::FileSystem reads tiles from disk via an internal FileSystemTileProtocol (the supplied protocol is not used).
• TileSource::Generator calls the TileGenerator registered with Self::with_generator; if none is set, an honest typed error is returned rather than silently falling back to the supplied protocol.

Implementations

impl StandardTileProvider

pub fn new(source: TileSource, protocol: Arc<dyn TileProtocol>) -> Self

Create a new tile provider.

For TileSource::FileSystem the protocol argument is unused (disk reads are handled internally); pass any protocol (e.g. a placeholder) or prefer routing through the source directly. For TileSource::Generator register a generator with Self::with_generator.

pub fn with_cache(self, cache: Arc<TileCache>) -> Self

Enable caching.

pub fn with_generator(self, generator: Arc<dyn TileGenerator>) -> Self

Register an in-memory tile generator, used when the source is TileSource::Generator.
