Struct CStream 

pub struct CStream { /* private fields */ }

The type of compressors.

Implementations

impl CStream

pub fn new(level: usize) -> Result<Self, Error>

pub fn in_size() -> usize

pub fn out_size() -> usize

pub fn compress( &mut self, output: &mut [u8], input: &[u8], ) -> Result<(usize, usize, usize), Error>

Compress one chunk of input, and write it into the output. The output array must be large enough to hold the result. If successful, this function returns three integers (out_pos, in_pos, next_read_size), where out_pos is the number of bytes written in output, in_pos is the number of input bytes consumed, and next_read_size is a hint for the next read size.

pub fn compress2( &mut self, output: &mut [u8], input: &[u8], op: EndDirective, ) -> Result<(usize, usize, usize), Error>

pub fn flush(&mut self, output: &mut [u8]) -> Result<(usize, usize), Error>

pub fn end(&mut self, output: &mut [u8]) -> Result<usize, Error>

Finish writing the message, i.e. write the remaining pending block.

Trait Implementations

impl Drop for CStream

fn drop(&mut self)
