pub struct ZlibEncoder<W> { /* private fields */ }Expand description
A zlib encoder, or compressor.
This structure implements an AsyncWrite interface and will
take in uncompressed data and write it compressed to an underlying stream.
Implementations§
source§impl<W> ZlibEncoder<W>where
W: AsyncWrite,
impl<W> ZlibEncoder<W>where
W: AsyncWrite,
sourcepub fn new(inner: W) -> ZlibEncoder<W>
pub fn new(inner: W) -> ZlibEncoder<W>
Creates a new encoder which will take in uncompressed data and write it compressed to the given stream.
sourcepub fn with_quality(inner: W, level: Level) -> ZlibEncoder<W>
pub fn with_quality(inner: W, level: Level) -> ZlibEncoder<W>
Creates a new encoder which will take in uncompressed data and write it compressed to the given stream.
sourcepub fn total_in(&self) -> u64
pub fn total_in(&self) -> u64
Returns the total number of input bytes which have been processed by this compression object.
sourcepub fn total_out(&self) -> u64
pub fn total_out(&self) -> u64
Returns the total number of output bytes which have been produced by this compression object.
sourcepub fn get_ref(&self) -> &W
pub fn get_ref(&self) -> &W
Acquires a reference to the underlying writer that this encoder is wrapping.
sourcepub fn get_mut(&mut self) -> &mut W
pub fn get_mut(&mut self) -> &mut W
Acquires a mutable reference to the underlying writer that this encoder is wrapping.
Note that care must be taken to avoid tampering with the state of the writer which may otherwise confuse this encoder.
sourcepub fn get_pin_mut(self: Pin<&mut ZlibEncoder<W>>) -> Pin<&mut W>
pub fn get_pin_mut(self: Pin<&mut ZlibEncoder<W>>) -> Pin<&mut W>
Acquires a pinned mutable reference to the underlying writer that this encoder is wrapping.
Note that care must be taken to avoid tampering with the state of the writer which may otherwise confuse this encoder.
sourcepub fn into_inner(self) -> W
pub fn into_inner(self) -> W
Consumes this encoder returning the underlying writer.
Note that this may discard internal state of this encoder, so care should be taken to avoid losing resources when this is called.
