Trait Implementations

impl Clone for GrePacket

fn clone(&self) -> GrePacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GrePacket

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

Formats the value using the given formatter.

impl Packet for GrePacket

type Header = ()

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

Parse from a byte slice.

fn from_bytes(bytes: Bytes) -> Option<Self>

Parse from raw bytes. (with ownership)

fn to_bytes(&self) -> Bytes

Serialize into raw bytes.

fn header(&self) -> Bytes

Get the header of the packet.

fn payload(&self) -> Bytes

Get the payload of the packet.

fn header_len(&self) -> usize

Get the length of the header.

fn payload_len(&self) -> usize

Get the length of the payload.

fn total_len(&self) -> usize

Get the total length of the packet (header + payload).

fn into_parts(self) -> (Self::Header, Bytes)

fn to_bytes_mut(&self) -> BytesMut

Convert the packet to a mutable byte buffer.

fn header_mut(&self) -> BytesMut

Get a mutable byte buffer for the header.

fn payload_mut(&self) -> BytesMut

Get a mutable byte buffer for the payload.

impl PartialEq for GrePacket

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