Module chunks 

Fixed-size plaintext chunks and bounded reconstruction of individual frames.

Structs

FrameDecoder

Holds only one unfinished frame. A known remaining length lets the write decoder refuse a frame that crosses its part’s end before reserving memory.

PlaintextChunks

Cut a sequence of bounded byte pieces into fixed-size chunks, retaining at most one frame and one output chunk. Only the last chunk may be shorter than CHUNK_SIZE.

Constants

CHUNK_SIZE

Plaintext bytes in a full file, write-part or snapshot chunk.

Functions

chunk_count

How many chunks length plaintext bytes cut into; none when empty.

chunk_length

The plaintext length of chunk index of length bytes: full, except a shorter last chunk. The caller keeps index below the chunk count.

chunk_start

Where chunk index begins in the plaintext.
