Struct ZlibStream 

pub struct ZlibStream { /* private fields */ }

An incremental zlib (RFC 1950) decompressor.

Wraps Inflater with the two-byte header, the running Adler-32 and the four-byte trailer. The checksum is computed as output is produced, so verifying it costs nothing extra and does not require retaining the output.

Implementations

impl ZlibStream

pub fn new(limit: usize) -> ZlibStream

A decompressor that will produce at most limit bytes.

pub fn push(&mut self, data: &[u8]) -> Result<Vec<u8>, Error>

Supply more compressed bytes and return whatever they decoded to.

Errors

Returns Error for a bad header, an unsupported compression method, or any DEFLATE error.

pub fn finish(&mut self) -> Result<Vec<u8>, Error>

Declare the input over and verify the checksum.

Errors

Returns Error if the stream ended mid-symbol, if the trailer is missing, or if the Adler-32 does not match.

Trait Implementations

impl Debug for ZlibStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
