Crate vortex_fastlanes 

FastLanes integer encodings for Vortex arrays.

This crate provides SIMD-friendly integer encodings:

• BitPacked stores fixed-width integer values using the minimum bit width plus optional patches.
• FoR stores frame-of-reference deltas from a base value.
• Delta stores adjacent deltas in chunked form.
• RLE stores repeated runs.

Call initialize to register the encodings and encoding-specific aggregate kernels in a session before deserializing or executing arrays that may contain these encodings.

let session = vortex_array::array_session();
vortex_fastlanes::initialize(&session);

Paper

The original encodings are described in the paper The FastLanes Compression Layout, but are not fully binary compatible. See the underlying fastlanes crate for more details.
