Struct IpcMessageHeader 

pub struct IpcMessageHeader {
    pub length: u32,
    pub message_type: MessageType,
}

Header for IPC messages, used for framing on the wire.

The header precedes every message and allows the receiver to:

1. Know how many bytes to read for the payload
2. Quickly determine message type without full deserialization

Fields

length: u32

Total length of the payload (not including header)

message_type: MessageType

Type of message (mirrors CommandMessage.message_type for quick routing)

Implementations

impl IpcMessageHeader

pub const SIZE: usize = 5

Size of the header in bytes (4 bytes length + 1 byte type)

pub fn new(message_type: MessageType, payload_length: u32) -> Self

Create a new header

pub fn from_message(msg: &CommandMessage) -> Result<Self, Error>

Create a header from a CommandMessage (extracts type and computes length)

pub fn to_bytes(&self) -> [u8; 5]

Serialize header to bytes (little-endian)

pub fn from_bytes(bytes: &[u8; 5]) -> Self

Deserialize header from bytes
