Struct ZlibDecoder 

Source 
pub struct ZlibDecoder<S> { /* private fields */ }
👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Available on crate features stream and zlib only.
Expand description

A zlib decoder, or decompressor.

This structure implements a Stream interface and will read compressed data from an underlying stream and emit a stream of uncompressed data.

Implementations§

Source§

impl<S: Stream<Item = Result<Bytes>>> ZlibDecoder<S>

Source

pub fn new(stream: S) -> Self

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Creates a new decoder which will read compressed data from the given stream and emit an uncompressed stream.

Source

pub fn multiple_members(&mut self, enabled: bool)

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Configure multi-member/frame decoding, if enabled this will reset the decoder state when reaching the end of a compressed member/frame and expect either the end of the wrapped stream or another compressed member/frame to follow.

Source

pub fn get_ref(&self) -> &S

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Acquires a reference to the underlying stream that this decoder is wrapping.

Source

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

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Acquires a mutable reference to the underlying stream that this decoder is wrapping.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this decoder.

Source

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut S>

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Acquires a pinned mutable reference to the underlying stream that this decoder is wrapping.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this decoder.

Source

pub fn into_inner(self) -> S

👎Deprecated since 0.3.8:

See async-compression::stream docs for migration

Consumes this decoder returning the underlying stream.

Note that this may discard internal state of this decoder, so care should be taken to avoid losing resources when this is called.
