Struct BtrBlocksCompressor 

pub struct BtrBlocksCompressor {
    pub int_schemes: Vec<&'static dyn IntegerScheme>,
    pub float_schemes: Vec<&'static dyn FloatScheme>,
    pub string_schemes: Vec<&'static dyn StringScheme>,
}

The main compressor type implementing BtrBlocks-inspired compression.

This compressor applies adaptive compression schemes to arrays based on their data types and characteristics. It recursively compresses nested structures like structs and lists, and chooses optimal compression schemes for primitive types.

The compressor works by:

1. Canonicalizing input arrays to a standard representation
2. Analyzing data characteristics to choose optimal compression schemes
3. Recursively compressing nested structures
4. Applying type-specific compression for primitives, strings, and temporal data

Use BtrBlocksCompressorBuilder to configure which compression schemes are enabled.

Examples

use vortex_btrblocks::{BtrBlocksCompressor, BtrBlocksCompressorBuilder, IntCode};

// Default compressor - all schemes allowed
let compressor = BtrBlocksCompressor::default();

// Exclude specific schemes using the builder
let compressor = BtrBlocksCompressorBuilder::default()
    .exclude_int([IntCode::Dict])
    .build();

Fields

int_schemes: Vec<&'static dyn IntegerScheme>

Integer compressor with configured schemes.

float_schemes: Vec<&'static dyn FloatScheme>

Float compressor with configured schemes.

string_schemes: Vec<&'static dyn StringScheme>

String compressor with configured schemes.

Implementations

impl BtrBlocksCompressor

pub fn compress(&self, array: &dyn Array) -> VortexResult<ArrayRef>

Compresses an array using BtrBlocks-inspired compression.

First canonicalizes and compacts the array, then applies optimal compression schemes.
