}

Interface for the compressor.

Required Methods

fn level(&self) -> usize

Get compression level of this compressor.

fn set_level(&mut self, level: usize)

Set compression level of this compressor.

fn try_compress( &mut self, buf: &[u8], preallocated: &mut Vec<u8>, ) -> Result<NonZeroUsize, CompressError>

Tries to compress buffer buf to the preallocated Vec.

Maximum compressed size is assumed to be Vec::capacity.

fn supported_levels(&self) -> RangeInclusive<usize>

Get backend’s supported compression levels.
