Struct FrameHeader 

pub struct FrameHeader {
    pub magic: u32,
    pub version: u16,
    pub length: u32,
    pub checksum: u32,
}

Frame header containing metadata about the payload.

Fields

magic: u32

Protocol magic bytes.

version: u16

Protocol version.

length: u32

Payload length in bytes.

checksum: u32

CRC32 checksum of the payload.

Implementations

impl FrameHeader

pub fn new(payload: &[u8]) -> Self

Creates a new frame header for the given payload.

pub fn encode(&self, buf: &mut BytesMut)

Encodes the header to bytes.

pub fn decode(buf: &mut impl Buf) -> Option<Self>

Decodes a header from bytes.

Returns None if there aren’t enough bytes.

pub fn validate(&self) -> WireResult<()>

Validates the header.

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.
