Expand description

Preforms write operations on an asset storage. AssetWriter exposes a “virtual filesystem” API, where asset bytes and asset metadata bytes are both stored and accessible for a given path. This trait is not object safe, if needed use a dyn ErasedAssetWriter instead.

Also see AssetReader.

Required Methods§

source

fn write<'a>( &'a self, path: &'a Path ) -> impl ConditionalSendFuture<Output = Result<Box<Writer>, AssetWriterError>>

Writes the full asset bytes at the provided path.

source

fn write_meta<'a>( &'a self, path: &'a Path ) -> impl ConditionalSendFuture<Output = Result<Box<Writer>, AssetWriterError>>

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

source

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

Removes the asset stored at the given path.

source

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

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

source

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

Renames the asset at old_path to new_path

source

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

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

source

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

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

source

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

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.

source

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

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

Provided Methods§

source

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

Writes the asset bytes to the given path.

source

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

Writes the asset meta bytes to the given path.

Object Safety§

This trait is not object safe.
