Struct MessageHeader 

pub struct MessageHeader {
    pub version: u8,
    pub message_type: MessageType,
    pub priority: Priority,
    pub sequence: u32,
    pub timestamp: u32,
    pub context_version: u32,
}

Message header (13 bytes total)

Fields

version: u8

Protocol version (2 bits in header byte)

message_type: MessageType

Message type (3 bits in header byte)

priority: Priority

Priority level (3 bits in header byte)

sequence: u32

Sequence number

timestamp: u32

Timestamp

context_version: u32

Context version used for encoding

Implementations

impl MessageHeader

pub const SIZE: usize = 13

Header size in bytes

pub fn new(message_type: MessageType, priority: Priority) -> Self

Create a new header with default values

pub fn encode_header_byte(&self) -> u8

Encode the header byte (version + type + priority)

pub fn decode_header_byte( byte: u8, ) -> (u8, Option<MessageType>, Option<Priority>)

Decode the header byte

pub fn to_bytes(&self) -> [u8; 13]

Serialize header to bytes

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserialize header from bytes

Trait Implementations

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MessageHeader

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for MessageHeader

fn eq(&self, other: &MessageHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
