}

Equivalent to an AssetReader but using boxed futures, necessary eg. when using a dyn AssetReader, as AssetReader isn’t currently object safe.

Required Methods

fn read<'a>( &'a self, path: &'a Path, ) -> BoxedFuture<'_, Result<Box<Reader<'a>>, AssetReaderError>>

Returns a future to load the full file data at the provided path.

fn read_meta<'a>( &'a self, path: &'a Path, ) -> BoxedFuture<'_, Result<Box<Reader<'a>>, AssetReaderError>>

Returns a future to load the full file data at the provided path.

fn read_directory<'a>( &'a self, path: &'a Path, ) -> BoxedFuture<'_, Result<Box<PathStream>, AssetReaderError>>

Returns an iterator of directory entry names at the provided path.

fn is_directory<'a>( &'a self, path: &'a Path, ) -> BoxedFuture<'_, Result<bool, AssetReaderError>>

Returns true if the provided path points to a directory.

fn read_meta_bytes<'a>( &'a self, path: &'a Path, ) -> BoxedFuture<'_, Result<Vec<u8>, AssetReaderError>>

Reads asset metadata bytes at the given path into a Vec<u8>. This is a convenience function that wraps ErasedAssetReader::read_meta by default.
