impl LevelSource for AnvilLevelSource

fn request_chunk_load(
    &mut self,
    req: ChunkLoadRequest
) -> Result<(), (LevelSourceError, ChunkLoadRequest)>

Request loading of the chunk at the given position. If you return an error, you must return back the given ChunkInfo together with the LevelSourceError. If you return Ok(()) you must give a result later when calling poll_chunk. This operation must be non-blocking.

fn poll_chunk(
    &mut self
) -> Option<Result<ProtoChunk, (LevelSourceError, ChunkLoadRequest)>>

Poll the next loaded chunk that is ready to be inserted into the level’s chunk storage. Every requested load chunk request_chunk_load method that returned Ok(()) should return some some result here, even if it’s an error. This operation must be non-blocking.

fn request_chunk_save(
