Struct detect_compression::DetectWriter

pub struct DetectWriter { /* fields omitted */ }

The Write type writes to compressed or uncompressed file.

This writer detects compression algorithms from file name extension.

You must finalize this writer.

Methods

impl DetectWriter

pub fn create<P: AsRef<Path>>(path: P, level: Level) -> Result<DetectWriter>

Create compressed or uncompressed file.

pub fn create_with_wrapper<P: AsRef<Path>, B: WriteWrapperBuilder>(
    path: P,
    level: Level,
    builder: B
) -> Result<DetectWriter>

Create compressed or uncompressed file using wrapper type.

InnerWriteWrapper is the wrapepr type's trait handles compressed byte stream. For example, the size-accumulating wrapper enables you to calculate size of compressed output.

pub fn finalize(self) -> Result<()>

Finalize this writer.

Some encodings requires finalization.

Trait Implementations

impl Drop for DetectWriter

fn drop(&mut self)

Executes the destructor for this type.

impl Write for DetectWriter

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

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

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

Flush 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 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, fmt: Arguments) -> Result<(), Error>

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

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

Creates a "by reference" adaptor for this instance of Write.
