Module framing 

Wire framing: a 4-byte big-endian length prefix and a UTF-8 JSON body.

The declared length is checked against the ceiling before any body is decoded, and the first violation poisons the decoder for good: resynchronising on an attacker-chosen offset is worse than dropping the connection.

Structs

Frame

One decoded wire frame: the raw body plus its parsed value.

FrameDecoder

Streaming decoder for length-prefixed JSON frames.

Constants

FRAME_HEADER_BYTES

Size of the length prefix that precedes every frame body.

Functions

decode_body

Decode and check one frame body.

encode_frame

Serialise a value into one length-prefixed frame.

project_dto

Check an untrusted parsed value against the DTO rules.
