Struct FrameHeader 

pub struct FrameHeader {
    pub version: u8,
    pub transport_tier: u8,
    pub msg_type: MsgType,
    pub sequence: u32,
    pub payload_len: u32,
}

Parsed representation of the 11-byte frame header.

Fields

version: u8

Protocol version (always PROTOCOL_VERSION).

transport_tier: u8

Transport identifier: 0=protocol (reserved for future use).

msg_type: MsgType

Message type tag.

sequence: u32

Monotonically increasing sequence number (LE).

payload_len: u32

Length of the payload that follows this header (LE).

Implementations

impl FrameHeader

pub fn write_to(&self, buf: &mut Vec<u8>)

Serialise the header into buf (appends exactly FRAME_HEADER_SIZE bytes).

pub fn read_from(data: &[u8]) -> Option<Self>

Attempt to parse a header from the first 11 bytes of data.

Returns None if data is shorter than FRAME_HEADER_SIZE.

Trait Implementations

impl Clone for FrameHeader

fn clone(&self) -> FrameHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameHeader

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

Formats the value using the given formatter.

impl PartialEq for FrameHeader

fn eq(&self, other: &FrameHeader) -> 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.
