Enum PaymentFailureReason

pub enum PaymentFailureReason {
    RecipientRejected,
    UserAbandoned,
    RetriesExhausted,
    PaymentExpired,
    RouteNotFound,
    UnexpectedError,
    UnknownRequiredFeatures,
    InvoiceRequestExpired,
    InvoiceRequestRejected,

}

The reason the payment failed. Used in Event::PaymentFailed.

Variants

RecipientRejected

The intended recipient rejected our payment.

Also used for UnknownRequiredFeatures and InvoiceRequestRejected when downgrading to version prior to 0.0.124.

UserAbandoned

The user chose to abandon this payment by calling ChannelManager::abandon_payment.

RetriesExhausted

We exhausted all of our retry attempts while trying to send the payment, or we exhausted the Retry::Timeout if the user set one. If at any point a retry attempt failed while being forwarded along the path, an Event::PaymentPathFailed will have come before this.

PaymentExpired

The payment expired while retrying, based on the provided PaymentParameters::expiry_time.

Also used for InvoiceRequestExpired when downgrading to version prior to 0.0.124.

RouteNotFound

We failed to find a route while sending or retrying the payment.

Note that this generally indicates that we’ve exhausted the available set of possible routes - we tried the payment over a few routes but were not able to find any further candidate routes beyond those.

Also used for BlindedPathCreationFailed when downgrading to versions prior to 0.0.124.

UnexpectedError

This error should generally never happen. This likely means that there is a problem with your router.

UnknownRequiredFeatures

An invoice was received that required unknown features.

InvoiceRequestExpired

A Bolt12Invoice was not received in a reasonable amount of time.

InvoiceRequestRejected

An InvoiceRequest for the payment was rejected by the recipient.

BlindedPathCreationFailed

Failed to create a blinded path back to ourselves. We attempted to initiate payment to a static invoice but failed to create a reply path for our HeldHtlcAvailable message.

Trait Implementations

impl Clone for PaymentFailureReason

fn clone(&self) -> PaymentFailureReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PaymentFailureReason

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

Formats the value using the given formatter.

impl MaybeReadable for PaymentFailureReason

fn read<R>(reader: &mut R) -> Result<Option<PaymentFailureReason>, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl PartialEq for PaymentFailureReason

fn eq(&self, other: &PaymentFailureReason) -> 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 Writeable for PaymentFailureReason

fn write<W>(&self, writer: &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.
