Crate vortex_onpair 

Vortex string array backed by the OnPair short-string compression library, with cast and filter pushdown.

The default training preset is dict-12 (12 bits per token, dictionary capped at 4 096 entries). See onpair_compress for the entry point and OnPairArray for the resulting array type.

Structs

Bits

Code width: the maximum dictionary size is 2^bits. Validated to 9..=16 at construction, so a Bits always holds an in-range value.

Config

Training configuration. See DEFAULT_CONFIG for a reasonable starting point.

OnPair

Zero-sized VTable marker for the OnPair encoding.

OnPairData

Inner data for an OnPair-encoded array.

OnPairMetadata

Wire-format metadata persisted alongside the OnPair buffer + slot children.

OnPairSlots

OnPairSlotsView

Borrowed view of OnPairSlots.

Threshold

Dynamic-threshold sample fraction. Validated to (0.0, 1.0] at construction, so a Threshold always holds an in-range value.

Enums

OnPairError

Error returned by the public training and encoding API.

Constants

DEFAULT_DICT12_CONFIG

Default OnPair training configuration: 12-bit codes (“dict-12”).

Traits

OnPairArrayExt

Convenience methods on top of the macro-generated OnPairArraySlotsExt.

OnPairArraySlotsExt

Typed array accessors for OnPair.

Functions

onpair_compress

Compress a byte-string accessor (typically a VarBinArray or VarBinViewArray).

onpair_compress_array

Compress any ArrayRef whose canonical form is a string array, by first canonicalising to VarBinViewArray.

onpair_compress_array_default

Convenience: build a default ExecutionCtx from LEGACY_SESSION.

onpair_compress_iter

Compress an iterable of optional byte strings via the OnPair encoder.

Type Aliases

OnPairArray

An OnPair-encoded Vortex array.
