Struct lightning_invoice::Invoice

pub struct Invoice { /* private fields */ }

Represents a syntactically and semantically correct lightning BOLT11 invoice.

There are three ways to construct an Invoice:

1. using InvoiceBuilder
2. using Invoice::from_signed(SignedRawInvoice)
3. using str::parse::<Invoice>(&str)

Implementations

impl Invoice

pub fn into_signed_raw(self) -> SignedRawInvoice

Transform the Invoice into it’s unchecked version

pub fn check_signature(&self) -> Result<(), SemanticError>

Check that the invoice is signed correctly and that key recovery works

pub fn from_signed(
    signed_invoice: SignedRawInvoice
) -> Result<Self, SemanticError>

Constructs an Invoice from a SignedRawInvoice by checking all its invariants.

let signed = invoice.parse::<SignedRawInvoice>().unwrap();

assert!(Invoice::from_signed(signed).is_ok());

pub fn timestamp(&self) -> SystemTime

This is supported on crate feature std only.

Returns the Invoice’s timestamp (should equal its creation time)

pub fn duration_since_epoch(&self) -> Duration

Returns the Invoice’s timestamp as a duration since the Unix epoch

pub fn tagged_fields(
    &self
) -> FilterMap<Iter<'_, RawTaggedField>, fn(_: &RawTaggedField) -> Option<&TaggedField>>

Returns an iterator over all tagged fields of this Invoice.

(C-not exported) As there is not yet a manual mapping for a FilterMap

pub fn payment_hash(&self) -> &Hash

Returns the hash to which we will receive the preimage on completion of the payment

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

Return the description or a hash of it for longer ones

(C-not exported) because we don’t yet export InvoiceDescription

pub fn payee_pub_key(&self) -> Option<&PublicKey>

Get the payee’s public key if one was included in the invoice

pub fn payment_secret(&self) -> &PaymentSecret

Get the payment secret if one was included in the invoice

pub fn features(&self) -> Option<&InvoiceFeatures>

Get the invoice features if they were included in the invoice

pub fn recover_payee_pub_key(&self) -> PublicKey

Recover the payee’s public key (only to be used if none was included in the invoice)

pub fn expiry_time(&self) -> Duration

Returns the invoice’s expiry time, if present, otherwise DEFAULT_EXPIRY_TIME.

pub fn is_expired(&self) -> bool

This is supported on crate feature std only.

Returns whether the invoice has expired.

pub fn would_expire(&self, at_time: Duration) -> bool

Returns whether the expiry time would pass at the given point in time. at_time is the timestamp as a duration since the Unix epoch.

pub fn min_final_cltv_expiry(&self) -> u64

Returns the invoice’s min_final_cltv_expiry time, if present, otherwise DEFAULT_MIN_FINAL_CLTV_EXPIRY.

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

Returns a list of all fallback addresses

(C-not exported) as we don’t support Vec<&NonOpaqueType>

pub fn private_routes(&self) -> Vec<&PrivateRoute>

Returns a list of all routes included in the invoice

pub fn route_hints(&self) -> Vec<RouteHint>

Returns a list of all routes included in the invoice as the underlying hints

pub fn currency(&self) -> Currency

Returns the currency for which the invoice was issued

pub fn amount_milli_satoshis(&self) -> Option<u64>

Returns the amount if specified in the invoice as millisatoshis.
