Struct EntryWriter

pub struct EntryWriter<'a> { /* private fields */ }

A writer for a single entry in a tar archive.

This struct is returned by Builder::append_writer and provides a Write implementation for adding content to an archive entry.

After writing all data to the entry, it must be finalized either by explicitly calling EntryWriter::finish or by letting it drop.

Implementations

impl EntryWriter<'_>

pub fn finish(self) -> Result<(), Error>

Finish writing the current entry in the archive.

Trait Implementations

impl Drop for EntryWriter<'_>

fn drop(&mut self)

Executes the destructor for this type.

impl Write for EntryWriter<'_>

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

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

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

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.
