Struct mqtt::control::fixed_header::FixedHeader

pub struct FixedHeader {
    pub packet_type: PacketType,
    pub remaining_length: u32,
}

Fixed header for each MQTT control packet

Format:

7                          3                          0

| Remaining Length ...                                |
+-----------------------------------------------------+

Fields

packet_type: PacketType

Packet Type

remaining_length: u32

The Remaining Length is the number of bytes remaining within the current packet, including data in the variable header and the payload. The Remaining Length does not include the bytes used to encode the Remaining Length.

Implementations

impl FixedHeader

pub fn new(packet_type: PacketType, remaining_length: u32) -> FixedHeader

Trait Implementations

impl Clone for FixedHeader

fn clone(&self) -> FixedHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FixedHeader

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

Formats the value using the given formatter.

impl Decodable for FixedHeader

type Error = FixedHeaderError

type Cond = ()

fn decode_with<R: Read>( rdr: &mut R, _rest: () ) -> Result<FixedHeader, FixedHeaderError>

Decodes object with additional data (or hints)

fn decode<R: Read>(reader: &mut R) -> Result<Self, Self::Error>

where Self::Cond: Default,

Decodes object from reader

impl Encodable for FixedHeader

fn encode<W: Write>(&self, wr: &mut W) -> Result<(), Error>

Encodes to writer

fn encoded_length(&self) -> u32

Length of bytes after encoded

impl PartialEq for FixedHeader

fn eq(&self, other: &FixedHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
