Expand description

Trait that will compress column values

Required Methods§

source

fn decompress_to( &self, value: &[u8], dest: &mut Vec<u8>, ) -> Result<(), NippyJarError>

Appends decompressed data to the dest buffer. Requires dest to have sufficient capacity.

source

fn decompress(&self, value: &[u8]) -> Result<Vec<u8>, NippyJarError>

Returns decompressed data.

source

fn compress_to( &self, src: &[u8], dest: &mut Vec<u8>, ) -> Result<usize, NippyJarError>

Appends compressed data from src to dest. dest. Requires dest to have sufficient capacity.

Returns number of bytes written to dest.

source

fn compress(&self, src: &[u8]) -> Result<Vec<u8>, NippyJarError>

Compresses data from src

Provided Methods§

source

fn is_ready(&self) -> bool

Returns true if it’s ready to compress.

Example: it will return false, if zstd with dictionary is set, but wasn’t generated.

Object Safety§

This trait is not object safe.
