Module concat 

Source
Expand description

Concatenation of complete encoded Lance files.

This module owns compatibility checks and metadata relocation for copying already-encoded pages into a new ordinary Lance file. Callers retain responsibility for dataset-level grouping, transactions, and fallbacks.

Structs§

BlobTargetId
Caller-defined runtime identity of the final target for Blob-bearing parts.
DataFilePart
A complete ordinary Lance file validated for data-file concatenation.
EncodedFileInput
One complete immutable Lance file supplied to concat_files.
FileConcatOptions
Runtime controls for encoded-file concatenation.
FileConcatOutput
Metadata describing the complete file represented by a concat result.
FileConcatTarget
The exact file grammar and schema required for concatenated output.

Enums§

FileConcatReason
A compatibility reason that requires a caller-controlled decode/re-encode fallback.
FileConcatResult
Result of one encoded-file concatenation attempt.

Functions§

concat_data_file_parts
Concatenate validated data-file parts in caller-supplied row order.
concat_files
Concatenate complete compatible encoded files in the supplied order.
