[][src]Crate lightning_invoice

This crate provides data structures to represent lightning BOLT11 invoices and functions to create, encode and decode these. If you just want to use the standard en-/decoding functionality this should get you started:

  • For parsing use str::parse::<Invoice>(&self) (see the docs of impl FromStr for Invoice)
  • For constructing invoices use the InvoiceBuilder
  • For serializing invoices use the Display/ToString traits

Modules

constants

Tag constants as specified in BOLT11

Structs

Description

Description string

ExpiryTime

Positive duration that defines when (relatively to the timestamp) in the future the invoice expires

Invoice

Represents a syntactically and semantically correct lightning BOLT11 invoice.

InvoiceBuilder

Builder for Invoices. It's the most convenient and advised way to use this library. It ensures that only a semantically and syntactically correct Invoice can be built using it.

MinFinalCltvExpiry

min_final_cltv_expiry to use for the last HTLC in the route

PayeePubKey

Payee public key

PositiveTimestamp

A timestamp that refers to a date after 1 January 1970 which means its representation as UNIX timestamp is positive.

RawDataPart

Data of the RawInvoice that is encoded in the data part

RawHrp

Data of the RawInvoice that is encoded in the human readable part

RawInvoice

Represents an syntactically correct Invoice for a payment on the lightning network, but without the signature information. De- and encoding should not lead to information loss but may lead to different hashes.

Route

Private routing information

RouteHop

Node on a private route

Sha256

SHA-256 hash

Signature

Recoverable signature

SignedRawInvoice

Represents a signed RawInvoice with cached hash. The signature is not checked and may be invalid.

Enums

CreationError

Errors that may occur when constructing a new RawInvoice or Invoice

Currency

Enum representing the crypto currencies (or networks) supported by this library

Fallback

Fallback address in case no LN payment is possible

InvoiceDescription

Represents the description of an invoice which has to be either a directly included string or a hash of a description provided out of band.

ParseError

Errors that indicate what is wrong with the invoice. They have some granularity for debug reasons, but should generally result in an "invalid BOLT11 invoice" message for the user.

ParseOrSemanticError

Indicates that something went wrong while parsing or validating the invoice. Parsing errors should be mostly seen as opaque and are only there for debugging reasons. Semantic errors like wrong signatures, missing fields etc. could mean that someone tampered with the invoice.

RawTaggedField

Tagged field which may have an unknown tag

SemanticError

Errors that may occur when converting a RawInvoice to an Invoice. They relate to the requirements sections in BOLT #11

SiPrefix

SI prefixes for the human readable part

SignOrCreationError

When signing using a fallible method either an user-supplied SignError or a CreationError may occur.

TaggedField

Tagged field with known tag

Functions

check_platform

Call this function on startup to ensure that all assumptions about the platform are valid.
