Trait Implementations

impl<'a, const MAX_PROPERTIES: usize, const MAX_WILL_PROPERTIES: usize> Packet<'a> for ConnectPacket<'a, MAX_PROPERTIES, MAX_WILL_PROPERTIES>

fn new() -> Self

fn encode( &mut self, buffer: &mut [u8], buffer_len: usize, ) -> Result<usize, BufferError>

Method encode provide way how to transfer Packet struct into Byte array (buffer)

fn decode( &mut self, _buff_reader: &mut BuffReader<'a>, ) -> Result<(), BufferError>

Decode method is opposite of encode - decoding Byte array and mapping it into corresponding Packet struct

fn set_property_len(&mut self, value: u32)

Setter method for packet properties len - not all Packet types support this

fn get_property_len(&mut self) -> u32

Setter method for packet properties len - not all Packet types support this

fn push_to_properties(&mut self, property: Property<'a>)

Method enables pushing new property into packet properties

fn property_allowed(&mut self, property: &Property<'a>) -> bool

Returns if property is allowed for packet

fn set_fixed_header(&mut self, header: u8)

Setter for packet fixed header

fn set_remaining_len(&mut self, remaining_len: u32)

Setter for remaining len

fn add_properties<const MAX_PROPERTIES: usize>( &mut self, properties: &Vec<Property<'a>, MAX_PROPERTIES>, ) -> u32

Method enables adding properties from client config - each packet decides if property can be used with that or not

fn decode_properties( &mut self, buff_reader: &mut BuffReader<'a>, ) -> Result<(), BufferError>

Method is decoding Byte array pointing to properties into heapless Vec in packet. If decoding goes wrong method is returning Error

fn decode_fixed_header( &mut self, buff_reader: &mut BuffReader<'_>, ) -> Result<PacketType, BufferError>

Method is decoding packet header into fixed header part and remaining length
