Module protocol 

Protocol module - wire format, framing, and frame types.

This module implements the binary protocol for the data plane:

• 11-byte header encoding/decoding
• Frame buffer for accumulating partial reads
• Frame struct with typed accessors
• Header pool for zero-allocation encoding

Re-exports

pub use header_pool::encode_header_pooled;

pub use header_pool::with_header_pool;

pub use header_pool::HeaderPool;

Modules

flags

Flag constants for the protocol.

header_pool

Header buffer pool for zero-allocation header encoding.

Structs

Frame

A complete protocol frame.

FrameBuffer

Buffer for accumulating incoming bytes and extracting complete frames.

Header

Decoded header from wire format.

Constants

ABORT_METHOD_ID

Reserved method ID for ABORT signal.

ABSOLUTE_MAX_PAYLOAD_SIZE

Absolute maximum payload size (~2 GB, max i32).

DEFAULT_MAX_PAYLOAD_SIZE

Default maximum payload size (1 GB).

HEADER_POOL_SIZE

Header pool size for ring buffer optimization.

HEADER_SIZE

Header size in bytes (fixed, exactly 11).

RESERVED_METHOD_ID

Reserved method ID (never use).

Functions

build_frame

decode_header

Decode a header from bytes (standalone function).

encode_header

Encode a header to bytes (standalone function).

encode_header_into
