Module msgpack 

Minimal msgpack encoder/decoder for Resource advertisements and HMU packets.

Supports the subset needed by Reticulum’s Resource protocol:

• Nil, Bool, positive/negative fixint, uint8-64, int8-32
• fixstr, str8
• bin8, bin16, bin32
• fixarray, array16
• fixmap, map16

Structs

Entries

Entries of a validated map.

Items

Items of a validated array (or keys and values of a map, in order).

Enums

Error

Msgpack error.

Value

A msgpack value.

ValueRef

A decoded msgpack value borrowing from its input. Arrays and maps are validated when decoded (formats, nesting depth, UTF-8) and keep their encoded items, which ValueRef::array_items and ValueRef::map_entries decode on demand.

Functions

pack

Encode a Value to msgpack bytes.

pack_array_header

Append the header of an array of len items, as pack writes it.

pack_bin_into

Append binary data, as pack writes Value::Bin.

pack_ref_into

Append a value decoded by unpack_ref exactly as pack writes the Value that unpack decodes from the same bytes.

pack_str_map

Convenience: pack a map from string keys.

unpack

Decode a single msgpack value from the start of data. Returns (value, bytes_consumed).

unpack_exact

Decode a complete msgpack value, ensuring no trailing data.

unpack_exact_ref

Decode a complete msgpack value without copying it, ensuring no trailing data. Accepts and rejects exactly the inputs unpack_exact does.

unpack_ref

Decode one value from the start of data without copying, returning it and the bytes consumed. Nested arrays and maps are validated in full.
