Enum HandleInterceptedHtlcError 

Source 
#[non_exhaustive]
pub enum HandleInterceptedHtlcError {
    BlockHeight(LightningRpcError),
    UnsafeExpiry(UnsafeHtlcExpiry),
    IncomingContract(IncomingSmError),
    OperationIdMismatch {
        expected: OperationId,
        derived: OperationId,
    },
    Transaction(TransactionSubmitError),
}
Expand description

A failure to handle an HTLC the gateway intercepted.

The gateway buys the payment’s preimage from the federation by funding the incoming contract that the recipient offered. A replay of an HTLC circuit the gateway already handles is not a failure.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

BlockHeight(LightningRpcError)

The Lightning node could not report its current block height, which the HTLC’s expiry is checked against.

§

UnsafeExpiry(UnsafeHtlcExpiry)

The HTLC expires too soon for the gateway to settle it safely.

§

IncomingContract(IncomingSmError)

The federation’s offer for this payment could not be turned into an incoming contract: it did not arrive in time, violates the fee policy, does not match the HTLC, already has a funded contract, or the federation could not be asked.

§

OperationIdMismatch

The operation id derived while funding disagrees with the one derived from the payment hash. This is a bug in this module; it is reported instead of panicking so that the caller can fail the HTLC back.

Fields

§expected: OperationId

The id derived from the payment hash.

§derived: OperationId

The id the funding step derived.

§

Transaction(TransactionSubmitError)

The transaction funding the incoming contract could not be built or submitted.
