Struct DynWriter 

pub struct DynWriter<'a, W>(/* private fields */)
where
    W: Write;

Type for runtime polymorphism over whether encoding uncompressed or Zstd-compressed DBN records. Implements std::io::Write.

Implementations

impl<W> DynWriter<'_, W>

where W: Write,

pub fn new(writer: W, compression: Compression) -> Result<Self>

Creates a new instance of DynWriter which will wrap writer with compression.

Errors

This function returns an error if it fails to initialize the Zstd encoder.

pub fn with_compression_level(writer: W, level: i32) -> Result<Self>

Creates a new instance with zstd compression of the specified level.

Errors

This function returns an error if it fails to initialize the Zstd encoder.

pub fn get_mut(&mut self) -> &mut W

Returns a mutable reference to the underlying writer.

Trait Implementations

impl<W> Write for DynWriter<'_, W>

where W: Write,

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>

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

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

Attempts to write an entire buffer into this writer.

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

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

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

where Self: Sized,

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