Lz4Compressor

arrow_ipc::compression

Struct Lz4Compressor 

Source 
struct Lz4Compressor {
    encoder: FrameEncoder<Vec<u8>>,
}
Expand description

Reusable lz4 frame compressor, the lz4 counterpart of zstd::bulk::Compressor.

lz4_flex has no bulk frame API, so this wraps a [lz4_flex::frame::FrameEncoder] whose hash table and block buffers are retained across calls to Self::compress_to_buffer.

Fields§

§encoder: FrameEncoder<Vec<u8>>

Source

fn new() -> Self

Source

fn compress_to_buffer( &mut self, input: &[u8], output: &mut Vec<u8>, ) -> Result<(), ArrowError>
