Module dispatch 

Operation-level dispatch across fixed, RDW, and VB framing. Operation-level fixed/RDW dispatch for codec callers.

The framing crates own byte-level parsing and writing. This module owns the format choice used by codec operations and keeps the legacy single-record helpers available through crate::record.

Structs

BdwHeader

Parsed BDW header (block length + reserved).

FixedRecordReader

Fixed record reader for processing fixed-length records.

FixedRecordWriter

Fixed record writer for writing fixed-length records.

RDWRecord

An RDW record with header and payload bytes.

RDWRecordReader

RDW (Record Descriptor Word) record reader for variable-length records.

RDWRecordWriter

RDW record writer for variable-length records.

VbBlockReader

Bounded VB block reader yielding framed records.

VbBlockWriter

Deterministic VB block writer packing records in order.

VbRecord

One record framed inside a VB block.

Constants

BDW_HEADER_LEN

Size of a BDW (Block Descriptor Word) header in bytes.

BDW_MAX_BLOCK_LEN

Maximum VB block length in bytes, header included.

RDW_HEADER_LEN

Size of an RDW header in bytes.

VB_MAX_RECORD_LEN

Maximum RDW length inside a VB block, header included.

Functions

read_rdw_record

Read one complete RDW record, preserving its header and reserved bytes.
