Enum CompressedWriter 

pub enum CompressedWriter {
    Gzip(GzEncoder<File>),
    Zlib(ZlibEncoder<File>),
    Zstd(Encoder<'static, File>),
    Brotli(CompressorWriter<File>),
}

Encoder wrapper that provides a uniform interface for different compression formats.

This enum wraps the various compression encoders so we can treat them uniformly in the append-to-compressed-archive flow.

Variants

Gzip(GzEncoder<File>)

Zlib(ZlibEncoder<File>)

Zstd(Encoder<'static, File>)

Brotli(CompressorWriter<File>)

Implementations

impl CompressedWriter

pub fn new(format: CompressionFormat, file: File) -> Result<Self, Diagnostic>

Create a new compressed writer for the given format and file.

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

Finish compression and return any errors.

This must be called before the file is closed to ensure all compressed data is flushed.

Trait Implementations

impl Write for CompressedWriter

Available on crate feature compression only.

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