Struct InnerOnionDataRequest

pub struct InnerOnionDataRequest {
    pub destination_pk: PublicKey,
    pub nonce: Nonce,
    pub temporary_pk: PublicKey,
    pub payload: Vec<u8>,
}

It’s used to send data requests to dht node using onion paths.

When DHT node receives OnionDataRequest it sends OnionDataResponse to destination node for which data request is intended. Thus, data request will go through 7 intermediate nodes until destination node gets it - 3 nodes with OnionRequests, onion node that handles OnionDataRequest and 3 nodes with OnionResponses.

Serialized form:

Length	Content
1	0x85
32	PublicKey of destination node
24	Nonce
32	Temporary PublicKey
variable	Payload

Fields

destination_pk: PublicKey

PublicKey of destination node

nonce: Nonce

Nonce for the current encrypted payload

temporary_pk: PublicKey

Temporary PublicKey for the current encrypted payload

payload: Vec<u8>

Encrypted payload

Implementations

impl InnerOnionDataRequest

pub fn new( shared_secret: &PrecomputedKey, destination_pk: PublicKey, temporary_pk: PublicKey, nonce: Nonce, payload: &OnionDataResponsePayload, ) -> InnerOnionDataRequest

Create InnerOnionDataRequest from OnionDataResponsePayload encrypting it with shared_key and nonce

pub fn get_payload( &self, shared_secret: &PrecomputedKey, ) -> Result<OnionDataResponsePayload, GetPayloadError>

Decrypt payload and try to parse it as OnionDataResponsePayload. Returns Error in case of failure:

• fails to decrypt
• fails to parse as OnionDataResponsePayload

Trait Implementations

impl Clone for InnerOnionDataRequest

fn clone(&self) -> InnerOnionDataRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InnerOnionDataRequest

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

Formats the value using the given formatter.

impl FromBytes for InnerOnionDataRequest

fn from_bytes( i: &[u8], ) -> IResult<&[u8], InnerOnionDataRequest, (&[u8], ErrorKind)>

Deserialize struct using nom from raw bytes

impl PartialEq for InnerOnionDataRequest

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