impl AssetReader for MemoryAssetReader

source§

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

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

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

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

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

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

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

Returns true if the provided path points to a directory.
source§

fn read_meta_bytes<'a>( &'a self, path: &'a Path ) -> impl ConditionalSendFuture<Output = Result<Vec<u8>, AssetReaderError>>

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

impl<T> Downcast for T
where T: Any,

source§

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

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.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

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