Struct BlindedPath 

pub struct BlindedPath {
    pub introduction_node_id: PublicKey,
    pub blinding_point: PublicKey,
    pub blinded_hops: Vec<BlindedHop>,
}

Onion messages and payments can be sent and received to blinded paths, which serve to hide the identity of the recipient.

Fields

introduction_node_id: PublicKey

To send to a blinded path, the sender first finds a route to the unblinded introduction_node_id, which can unblind its encrypted_payload to find out the onion message or payment’s next hop and forward it along.

blinding_point: PublicKey

Used by the introduction node to decrypt its encrypted_payload to forward the onion message or payment.

blinded_hops: Vec<BlindedHop>

The hops composing the blinded path.

Implementations

impl BlindedPath

pub fn one_hop_for_message<ES, T>( recipient_node_id: PublicKey, entropy_source: &ES, secp_ctx: &Secp256k1<T>, ) -> Result<BlindedPath, ()>

where ES: EntropySource + ?Sized, T: Signing + Verification,

Create a one-hop blinded path for a message.

pub fn new_for_message<ES, T>( node_pks: &[PublicKey], entropy_source: &ES, secp_ctx: &Secp256k1<T>, ) -> Result<BlindedPath, ()>

where ES: EntropySource + ?Sized, T: Signing + Verification,

Create a blinded path for an onion message, to be forwarded along node_pks. The last node pubkey in node_pks will be the destination node.

Errors if no hops are provided or if node_pk(s) are invalid.

pub fn one_hop_for_payment<ES, T>( payee_node_id: PublicKey, payee_tlvs: ReceiveTlvs, entropy_source: &ES, secp_ctx: &Secp256k1<T>, ) -> Result<(BlindedPayInfo, BlindedPath), ()>

where ES: EntropySource + ?Sized, T: Signing + Verification,

Create a one-hop blinded path for a payment.

Trait Implementations

impl Clone for BlindedPath

fn clone(&self) -> BlindedPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlindedPath

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

Formats the value using the given formatter.

impl Hash for BlindedPath

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BlindedPath

fn eq(&self, other: &BlindedPath) -> 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 Readable for BlindedPath

fn read<R>(r: &mut R) -> Result<BlindedPath, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl Writeable for BlindedPath

fn write<W>(&self, w: &mut W) -> Result<(), Error>

where W: Writer,

Writes self out to the given Writer.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
