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

Required Methods

fn write<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<Box<dyn AsyncWrite + Unpin + Sync + Send>, AssetWriterError>> + 'a>>

Writes the full asset bytes at the provided path.

fn write_meta<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<Box<dyn AsyncWrite + Unpin + Sync + Send>, AssetWriterError>> + 'a>>

Writes the full asset meta bytes at the provided path. This should not include storage specific extensions like .meta.

fn remove<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Removes the asset stored at the given path.

fn remove_meta<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Removes the asset meta stored at the given path. This should not include storage specific extensions like .meta.

fn rename<'a>( &'a self, old_path: &'a Path, new_path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Renames the asset at old_path to new_path

fn rename_meta<'a>( &'a self, old_path: &'a Path, new_path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Renames the asset meta for the asset at old_path to new_path. This should not include storage specific extensions like .meta.

fn remove_directory<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Removes the directory at the given path, including all assets and directories in that directory.

fn remove_empty_directory<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Removes the directory at the given path, but only if it is completely empty. This will return an error if the directory is not empty.

fn remove_assets_in_directory<'a>( &'a self, path: &'a Path ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Removes all assets (and directories) in this directory, resulting in an empty directory.

fn write_bytes<'a>( &'a self, path: &'a Path, bytes: &'a [u8] ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Writes the asset bytes to the given path.

fn write_meta_bytes<'a>( &'a self, path: &'a Path, bytes: &'a [u8] ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<(), AssetWriterError>> + 'a>>

Writes the asset meta bytes to the given path.
