Struct NodesRequest

pub struct NodesRequest {
    pub pk: PublicKey,
    pub nonce: Nonce,
    pub payload: Vec<u8>,
}

Nodes request packet struct. It’s used to get up to 4 closest nodes to requested public key. Every 20 seconds DHT node sends NodesRequest packet to a random node in ktree and its known friends list.

encrypted payload

Implementations

impl NodesRequest

pub fn new( shared_secret: &PrecomputedKey, pk: &PublicKey, payload: &NodesRequestPayload, ) -> NodesRequest

create new NodesRequest object

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

Decrypt payload and try to parse it as NodesRequestPayload.

Returns Error in case of failure:

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

Trait Implementations

impl Clone for NodesRequest

fn clone(&self) -> NodesRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodesRequest

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

Formats the value using the given formatter.

impl FromBytes for NodesRequest

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

Deserialize struct using nom from raw bytes

impl PartialEq for NodesRequest

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

impl ToBytes for NodesRequest

fn to_bytes<'a>( &self, buf: (&'a mut [u8], usize), ) -> Result<(&'a mut [u8], usize), GenError>

Serialize struct into raw bytes using cookie_factory

impl Eq for NodesRequest
