Struct FrameHeader 

pub struct FrameHeader {
    pub frame_type: FrameType,
    pub version: u8,
    pub compressed: bool,
    pub fragmented: bool,
    pub payload_length: u32,
}

Frame header structure

Layout (8 bytes):

• Byte 0: Frame type (4 bits) | Protocol version (4 bits)
• Byte 1: Flags (compressed: 1 bit, fragmented: 1 bit, reserved: 6 bits)
• Bytes 2-5: Payload length (u32, big-endian)
• Bytes 6-7: Reserved

Fields

frame_type: FrameType

Frame type

version: u8

Protocol version

compressed: bool

Compressed flag

fragmented: bool

Fragmented flag

payload_length: u32

Payload length

Implementations

impl FrameHeader

pub const SIZE: usize = 8

pub fn encode(&self) -> [u8; 8]

Encode frame header to bytes

pub fn decode(data: &[u8]) -> Result<Self>

Decode frame header from bytes

pub fn total_size(&self) -> usize

Get total frame size (header + payload)
