Struct bevy::asset::io::file::FileAssetReader

pub struct FileAssetReader { /* private fields */ }
Expand description

I/O implementation for the local filesystem.

This asset I/O is fully featured but it’s not available on android and wasm targets.

Implementations§

§

impl FileAssetReader

pub fn new<P>(path: P) -> FileAssetReaderwhere P: AsRef<Path>,

Creates a new FileAssetIo at a path relative to the executable’s directory, optionally watching for changes.

See get_base_path below.

pub fn get_base_path() -> PathBuf

Returns the base path of the assets directory, which is normally the executable’s parent directory.

If the CARGO_MANIFEST_DIR environment variable is set, then its value will be used instead. It’s set by cargo when running with cargo run.

pub fn root_path(&self) -> &PathBuf

Returns the root directory where assets are loaded from.

See get_base_path.

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

fn read_meta<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn Future<Output = Result<Box<dyn AsyncRead + Sync + Unpin + Send + 'a, Global>, AssetReaderError>> + Send + 'a, Global>>

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

fn read_directory<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Stream<Item = PathBuf> + Unpin + Send, Global>, AssetReaderError>> + Send + 'a, Global>>

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

fn is_directory<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn Future<Output = Result<bool, AssetReaderError>> + Send + 'a, Global>>

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

fn read_meta_bytes<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn Future<Output = Result<Vec<u8, Global>, AssetReaderError>> + Send + 'a, Global>>

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

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
