TODO

• Allow users to switch to un-buffered mode if users write 16MiB every time.

Implementations

impl<W: AppendWrite> AppendWriter<W>

Safety

wasm32 is a special target that we only have one event-loop for this state.

pub fn new(inner: W) -> Self

Create a new AppendWriter.

Trait Implementations

impl<W> Write for AppendWriter<W>

where W: AppendWrite,

async fn write(&mut self, bs: Buffer) -> Result<()>

async fn close(&mut self) -> Result<Metadata>

Close the writer and make sure all data has been flushed.

async fn abort(&mut self) -> Result<()>

Abort the pending writer.

fn copy_from( &mut self, _path: &str, _args: OpRead, _range: BytesRange, ) -> impl Future<Output = Result<()>> + MaybeSend

Copy one absolute bounded source range into this writer.
