Module record 

Length-delimited record framing.

record := tag:u8 flags:u8 reserved:u16=0 length:u32 payload:[u8;length] crc32c:u32

The CRC covers the 8-byte record header and the payload. reserved must be zero. The flags bit FLAG_OPTIONAL marks a record whose tag a decoder may skip if unknown; unknown non-optional tags fail closed.

Structs

Record

A single decoded record.

RecordReader

An iterator over the records of a byte slice.

Enums

RecordTag

Known record classes.

Constants

FLAG_OPTIONAL

Flag: this record’s tag may be skipped by a decoder that does not know it.

RECORD_HEADER_LEN

Bytes of per-record framing before the payload.

RECORD_OVERHEAD

Total framing overhead per record.

RECORD_TRAILER_LEN

Bytes of per-record framing after the payload (the CRC).

Functions

read_record_at

Read and CRC-check exactly one record located at offset in a seekable source.

write_record

Append an encoded record to out. payload must fit in u32.
