Enum GatewaySendPaymentError 

Source 
#[non_exhaustive]
pub enum GatewaySendPaymentError {
    LightningNotConnected,
    NotOurContract,
    InvalidAuthSignature,
    Federation(Box<FederationError>),
    ContractNotConfirmed,
    ContractIdMismatch,
    MissingInvoiceAmount,
    PaymentHashMismatch,
    MinContractAmount(GatewayClientV2Error),
    PaymentImageAlreadyClaimed,
}
Expand description

A refusal to pay an invoice for an LNv2 client.

These are the checks the gateway makes before it starts paying. A payment that starts and is later cancelled is not a failure: it is reported as the forfeit signature in the Ok value.

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.
§

LightningNotConnected

The gateway is not connected to its lightning node, so a new send would sit waiting for it.

§

NotOurContract

The outgoing contract names another gateway’s key, so this gateway could never claim it.

§

InvalidAuthSignature

The request’s signature over the invoice does not verify against the contract’s refund key.

§

Federation(Box<FederationError>)

The federation could not be asked about the outgoing contract.

§

ContractNotConfirmed

The federation has not confirmed the outgoing contract yet.

§

ContractIdMismatch

The contract the federation confirmed at the request’s outpoint is not the one in the request.

§

MissingInvoiceAmount

The invoice carries no amount.

§

PaymentHashMismatch

The invoice’s payment hash is not the one the contract is locked to.

§

MinContractAmount(GatewayClientV2Error)

The gateway could not work out the smallest contract amount it accepts for this payment.

§

PaymentImageAlreadyClaimed

Another operation already claimed the contract’s payment image, so this gateway will never pay it out for this contract.
