Struct brotli2::CompressParams

pub struct CompressParams { /* fields omitted */ }

Parameters passed to various compression routines.

Methods

impl CompressParams

pub fn new() -> CompressParams

Creates a new default set of compression parameters.

pub fn mode(&mut self, mode: CompressMode) -> &mut CompressParams

Set the mode of this compression.

pub fn quality(&mut self, quality: u32) -> &mut CompressParams

Controls the compression-speed vs compression-density tradeoffs.

The higher the quality, the slower the compression. Currently the range for the quality is 0 to 11.

pub fn lgwin(&mut self, lgwin: u32) -> &mut CompressParams

Sets the base 2 logarithm of the sliding window size.

Currently the range is 10 to 24.

pub fn lgblock(&mut self, lgblock: u32) -> &mut CompressParams

Sets the base 2 logarithm of the maximum input block size.

Currently the range is 16 to 24, and if set to 0 the value will be set based on the quality.

pub fn get_lgblock_readable(&self) -> usize

Get the current block size

pub fn get_lgblock(&self) -> u32

Get the native lgblock size

pub fn get_lgwin_readable(&self) -> usize

Get the current window size

pub fn get_lgwin(&self) -> u32

Get the native lgwin value
