Struct BlindedPaymentPath

pub struct BlindedPaymentPath {
    pub payinfo: BlindedPayInfo,
    /* private fields */
}

A blinded path to be used for sending or receiving a payment, hiding the identity of the recipient.

Fields

payinfo: BlindedPayInfo

The BlindedPayInfo used to pay this blinded path.

Implementations

impl BlindedPaymentPath

pub fn one_hop<ES: Deref, T: Signing + Verification>( payee_node_id: PublicKey, payee_tlvs: ReceiveTlvs, min_final_cltv_expiry_delta: u16, entropy_source: ES, secp_ctx: &Secp256k1<T>, ) -> Result<Self, ()>

where ES::Target: EntropySource,

Create a one-hop blinded path for a payment.

pub fn new<ES: Deref, T: Signing + Verification>( intermediate_nodes: &[PaymentForwardNode], payee_node_id: PublicKey, payee_tlvs: ReceiveTlvs, htlc_maximum_msat: u64, min_final_cltv_expiry_delta: u16, entropy_source: ES, secp_ctx: &Secp256k1<T>, ) -> Result<Self, ()>

where ES::Target: EntropySource,

Create a blinded path for a payment, to be forwarded along intermediate_nodes.

Errors if:

• a provided node id is invalid
• BlindedPayInfo calculation results in an integer overflow
• any unknown features are required in the provided ForwardTlvs

pub fn public_introduction_node_id<'a>( &self, network_graph: &'a ReadOnlyNetworkGraph<'_>, ) -> Option<&'a NodeId>

Returns the introduction NodeId of the blinded path, if it is publicly reachable (i.e., it is found in the network graph).

pub fn introduction_node(&self) -> &IntroductionNode

The IntroductionNode of the blinded path.

pub fn blinding_point(&self) -> PublicKey

Used by the IntroductionNode to decrypt its encrypted_payload to forward the payment.

pub fn blinded_hops(&self) -> &[BlindedHop]

The BlindedHops within the blinded path.

pub fn advance_path_by_one<NS: Deref, NL: Deref, T>( &mut self, node_signer: &NS, node_id_lookup: &NL, secp_ctx: &Secp256k1<T>, ) -> Result<(), ()>

where NS::Target: NodeSigner, NL::Target: NodeIdLookUp, T: Signing + Verification,

Advance the blinded onion payment path by one hop, making the second hop into the new introduction node.

Will only modify self when returning Ok.

Trait Implementations

impl Clone for BlindedPaymentPath

fn clone(&self) -> BlindedPaymentPath

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlindedPaymentPath

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

Formats the value using the given formatter.

impl Hash for BlindedPaymentPath

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

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 BlindedPaymentPath

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