Module encode 

Network encoding of paletted container entries.

Entries are packed like vanilla SimpleBitStorage: 64 / bits entries per long, low bits first, no entry spanning two longs, longs written big-endian.

Structs

PaletteIndexTable 🔒

The thread’s index table filled with one palette, reset to empty when dropped (including on unwind) so the next palette starts from a clean table.

Constants

EMPTY_SLOT 🔒

Marks an index-table slot whose global id is not in the palette being encoded.

INDEX_TABLE_LEN 🔒

Global ids are u16-backed, so a table indexed by global id has this many slots.

MAX_PACKED_BYTES 🔒

Largest packed payload: a 16×16×16 section at 16 bits per entry.

PALETTE_INDEX 🔒

Palette index per global id, reused across encodes on this thread. It takes 128 KiB on each thread that encodes a section, allocated on first use.

Functions

invalid_data 🔒

pack 🔒

Packs values into buffer, failing if a value has no entry.

pack_global_ids 🔒

Packs each value’s global id into buffer and returns the packed bytes.

pack_longs 🔒

Packs values into the front of buffer, failing if a value has no entry.

pack_palette_indices 🔒

Packs each value’s index in palette into buffer and returns the packed bytes.
