Struct breez_sdk_liquid::lightning::offers::invoice::Bolt12Invoice

pub struct Bolt12Invoice { /* private fields */ }

A Bolt12Invoice is a payment request, typically corresponding to an Offer or a Refund.

An invoice may be sent in response to an InvoiceRequest in the case of an offer or sent directly after scanning a refund. It includes all the information needed to pay a recipient.

Implementations

impl Bolt12Invoice

pub fn description(&self) -> PrintableString<'_>

A complete description of the purpose of the originating offer or refund. Intended to be displayed to the user but with the caveat that it has not been verified in any way.

pub fn payment_paths(&self) -> &[(BlindedPayInfo, BlindedPath)]

Paths to the recipient originating from publicly reachable nodes, including information needed for routing payments across them.

Blinded paths provide recipient privacy by obfuscating its node id. Note, however, that this privacy is lost if a public node id is used for Bolt12Invoice::signing_pubkey.

This is not exported to bindings users as slices with non-reference types cannot be ABI matched in another language.

pub fn created_at(&self) -> Duration

Duration since the Unix epoch when the invoice was created.

pub fn relative_expiry(&self) -> Duration

Duration since Bolt12Invoice::created_at when the invoice has expired and therefore should no longer be paid.

pub fn is_expired(&self) -> bool

Whether the invoice has expired.

pub fn payment_hash(&self) -> PaymentHash

SHA256 hash of the payment preimage that will be given in return for paying the invoice.

pub fn amount_msats(&self) -> u64

The minimum amount required for a successful payment of the invoice.

pub fn fallbacks(&self) -> Vec<Address>

Fallback addresses for paying the invoice on-chain, in order of most-preferred to least-preferred.

pub fn features(&self) -> &Features<Bolt12InvoiceContext>

Features pertaining to paying an invoice.

pub fn signing_pubkey(&self) -> PublicKey

The public key corresponding to the key used to sign the invoice.

pub fn signature(&self) -> Signature

Signature of the invoice verified using Bolt12Invoice::signing_pubkey.

pub fn signable_hash(&self) -> [u8; 32]

Hash that was used for signing the invoice.

pub fn verify<T>(&self, key: &ExpandedKey, secp_ctx: &Secp256k1<T>) -> bool

where T: Signing,

Verifies that the invoice was for a request or refund created using the given key.

Trait Implementations

fn clone(&self) -> Bolt12Invoice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bolt12Invoice

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

Formats the value using the given formatter.

impl TryFrom<ParsedMessage<(PayerTlvStream, OfferTlvStream, InvoiceRequestTlvStream, InvoiceTlvStream, SignatureTlvStream)>> for Bolt12Invoice

type Error = Bolt12ParseError

The type returned in the event of a conversion error.

fn try_from( invoice: ParsedMessage<(PayerTlvStream, OfferTlvStream, InvoiceRequestTlvStream, InvoiceTlvStream, SignatureTlvStream)>, ) -> Result<Bolt12Invoice, <Bolt12Invoice as TryFrom<ParsedMessage<(PayerTlvStream, OfferTlvStream, InvoiceRequestTlvStream, InvoiceTlvStream, SignatureTlvStream)>>>::Error>

Performs the conversion.

impl TryFrom<Vec<u8>> for Bolt12Invoice
