Struct tox_packet::dht::DhtRequest

pub struct DhtRequest {
    pub rpk: PublicKey,
    pub spk: PublicKey,
    pub nonce: Nonce,
    pub payload: Vec<u8>,
}

DHT Request packet struct. DHT Request packet consists of NatPingRequest and NatPingResponse. When my known friend is not connected directly, send NatPingRequest to peers which are in Ktree. When NatPingResponse arrives to me, it means that my known friend is also searching me, and running behind NAT, so start hole-punching.

Implementations

impl DhtRequest

pub fn new(
    shared_secret: &PrecomputedKey,
    rpk: &PublicKey,
    spk: &PublicKey,
    dp: &DhtRequestPayload
) -> DhtRequest

create new DhtRequest object

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

Decrypt payload and try to parse it as packet type.

Returns Error in case of failure:

• fails to decrypt
• fails to parse as given packet type
