Struct Header

pub struct Header {
    pub typ: PacketType,
    pub dup: bool,
    pub qos: QoS,
    pub retain: bool,
    pub remaining_len: u32,
}

Fixed header type.

Fields

typ: PacketType

dup: bool

qos: QoS

retain: bool

remaining_len: u32

Implementations

impl Header

pub fn new( typ: PacketType, dup: bool, qos: QoS, retain: bool, remaining_len: u32, ) -> Self

pub fn new_with(hd: u8, remaining_len: u32) -> Result<Header, ErrorV5>

pub fn decode(reader: &[u8]) -> Result<Self, ErrorV5>

pub async fn decode_async<T: AsyncRead + Unpin>( reader: &mut T, ) -> Result<Self, ErrorV5>

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Hash for Header

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Header

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

impl PollHeader for Header

type Error = ErrorV5

type Packet = Packet

fn new_with(hd: u8, remaining_len: u32) -> Result<Self, Self::Error>

where Self: Sized,

fn build_empty_packet(&self) -> Option<Self::Packet>

Packet without body is empty packet

fn block_decode(self, reader: &mut &[u8]) -> Result<Self::Packet, Self::Error>

fn remaining_len(&self) -> usize

fn is_eof_error(err: &Self::Error) -> bool
