Struct UnsecuredHeader 

pub struct UnsecuredHeader {
    pub basic: BasicHeader,
    pub common: CommonHeader,
    pub extended: Option<ExtendedHeader>,
}

Helper struct for decoding unsecured GeoNetworking headers from JSON. This crate focuses on zero-copy decoding from binary packets, therefore, JSON deserialization features are limited to a subset of GeoNetworking types.

Fields

basic: BasicHeader

common: CommonHeader

extended: Option<ExtendedHeader>

Implementations

impl UnsecuredHeader

pub fn from_json(json: &str) -> Result<Self, DecodeError<&str>>

Tries to deserialize an unsecured GeoNetworking header from JSON.

Usage

let json_header = r#"{"basic":{"version":1,"next_header":"CommonHeader","reserved":0,"lifetime":80,"remaining_hop_limit":1},"secured":null,"common":{"next_header":"BTPB","reserved_1":0,"header_type_and_subtype":{"TopologicallyScopedBroadcast":"SingleHop"},"traffic_class":{"store_carry_forward":false,"channel_offload":false,"traffic_class_id":2},"flags":[false,false,false,false,false,false,false,false],"payload_length":8,"maximum_hop_limit":1,"reserved_2":0},"extended":{"SHB":{"source_position_vector":{"gn_address":{"manually_configured":false,"station_type":"Unknown","reserved":262,"address":[0,96,224,105,87,141]},"timestamp":542947520,"latitude":535574568,"longitude":99765648,"position_accuracy":false,"speed":680,"heading":2122},"media_dependent_data":[127,0,184,0]}}}"#;
let payload: &'static [u8] = &[0x00, 0x01, 0x02, 0x03, 0x00, 0x01, 0x02, 0x03];
let unsecured_header = UnsecuredHeader::from_json(json_header).unwrap();
let unsecured_packet: Packet = unsecured_header.with_payload(payload).expect("REASON");

Errors

Returns a DecodeError when parsing failed

pub fn with_payload(self, payload: &[u8]) -> Result<Packet<'_>, EncodeError>

Converts the UnsecuredHeader helper struct into a regular Packet::Unsecured. Takes a payload of the length specified in the GeoNetworking’s Common Header.

Errors

Returns an EncodeError when parsing failed
