Module codec 

COBS framing: encode/decode frames and accumulate partial reads.

Each frame is COBS-encoded and terminated with a 0x00 sentinel byte. The sentinel never appears in the encoded data, so it unambiguously marks frame boundaries.

Uses the ucobs crate — the same COBS implementation as the firmware.

Structs

FrameReader

Stateful COBS frame accumulator.

Functions

decode_frame

COBS-decode a frame (without the sentinel). Returns None on decode error.

encode_frame

COBS-encode data and append the 0x00 sentinel.

read_frame

Read one complete COBS frame from a blocking Read source.
