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

| MQTT Control Packet Type | Flags for each type      |
+--------------------------+--------------------------+
| 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.
