Struct CompressionTree

pub struct CompressionTree<'a> { /* private fields */ }

Implementations

impl<'a> CompressionTree<'a>

pub fn flat(compressor: &'a dyn EncodingCompressor) -> Self

pub fn new( compressor: &'a dyn EncodingCompressor, children: Vec<Option<CompressionTree<'a>>>, ) -> Self

pub fn child(&self, idx: usize) -> Option<&CompressionTree<'a>>

pub fn compress_unchecked( &self, array: &Array, ctx: &SamplingCompressor<'a>, ) -> VortexResult<CompressedArray<'a>>

Compresses array with our compressor without verifying that the compressor can compress this array

pub fn compress( &self, array: &Array, ctx: &SamplingCompressor<'a>, ) -> Option<VortexResult<CompressedArray<'a>>>

pub fn compressor(&self) -> &dyn EncodingCompressor

pub fn metadata(&mut self) -> Option<Arc<dyn EncoderMetadata>>

Access the saved opaque metadata.

This will consume the owned metadata, giving the caller ownership of the Box.

The value of T will almost always be EncodingCompressor-specific.

pub fn into_parts( self, ) -> (&'a dyn EncodingCompressor, Vec<Option<CompressionTree<'a>>>, Option<Arc<dyn EncoderMetadata>>)
