Struct ConnAck 

pub struct ConnAck(/* private fields */);

Represents an MQTT ConnAck packet.

The ConnAck packet is sent by the server to the client in response to a Connect request. It contains a ConnectReturnCode that indicates the result of the connection attempt.

Examples

use mqute_codec::protocol::v4::ConnectReturnCode;
use mqute_codec::protocol::v3::ConnAck;

let connack = ConnAck::new(ConnectReturnCode::Success);
let code = connack.code();
assert_eq!(code, ConnectReturnCode::Success);

Implementations

impl ConnAck

pub fn new(code: ConnectReturnCode) -> Self

Creates a new ConnAck packet with the specified return code.

pub fn code(&self) -> ConnectReturnCode

Returns the ConnectReturnCode contained in the ConnAck packet.

Trait Implementations

impl Clone for ConnAck

fn clone(&self) -> ConnAck

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnAck

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

Formats the value using the given formatter.

impl Decode for ConnAck

fn decode(packet: RawPacket) -> Result<Self, Error>

Decodes a raw MQTT packet into the implementing type.

impl Encode for ConnAck

fn encode(&self, buf: &mut BytesMut) -> Result<(), Error>

Encodes the packet into the provided buffer.

fn payload_len(&self) -> usize

Returns the length of the payload in bytes.

impl From<ConnAck> for Packet

fn from(value: ConnAck) -> Self

Converts to this type from the input type.

impl PartialEq for ConnAck

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