Struct PlainSink 

pub struct PlainSink(/* private fields */);

A Sink over a destination that needs no trailer — an uncompressed file.

Exists so Container::create can take a Box<dyn Sink> uniformly. A composed write never constructs one: there the codec’s own Sink IS the container’s destination. finish flushes, which is exactly what all four containers used to do by hand at the end of their own finish.

Implementations

impl PlainSink

pub fn new(w: Box<dyn Write + Send>) -> Box<dyn Sink>

Returns the boxed trait object rather than Self on purpose: every call site wants a Box<dyn Sink>, and handing back Self would make each of them re-box it.

Trait Implementations

impl Sink for PlainSink

fn finish(self: Box<Self>) -> Result<()>

impl Write for PlainSink

fn write(&mut self, b: &[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.
