Struct OutputSink 

pub struct OutputSink { /* private fields */ }

A streaming output sink for writing bytes to a storage backend.

This type abstracts over backend-specific sink implementations. Callers obtain a sink via open_output_sink and then stream bytes through the writer() handle. Finalization is explicit via finish() to allow backend-specific commit semantics (e.g., atomic rename or multipart upload).

Implementations

impl OutputSink

pub fn writer(&mut self) -> &mut dyn Write

Return a mutable Write handle for streaming bytes.

pub async fn finish(self) -> StorageResult<()>

Flush, fsync, and commit to final location.

Trait Implementations

impl Write for OutputSink

fn write(&mut self, bytes: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
