Trait fastanvil::RegionLoader

pub trait RegionLoader<C: Chunk>: Send + Sync {
    fn region(&self, x: RCoord, z: RCoord) -> Option<Box<dyn Region<C>>>;
    fn list(&self) -> LoaderResult<Vec<(RCoord, RCoord)>>;
}

RegionLoader implmentations provide access to regions. They do not need to be concerned with caching, just providing an object that implements Region.

An example implementation could be loading a region file from a local disk, or perhaps a WASM version loading from a file buffer in the browser.

Required methods

fn region(&self, x: RCoord, z: RCoord) -> Option<Box<dyn Region<C>>>

Get a particular region. Returns None if region does not exist.

fn list(&self) -> LoaderResult<Vec<(RCoord, RCoord)>>

List the regions that this loader can return. Implmentations need to provide this so that callers can efficiently find regions to process.
