Enum lightning::routing::utxo::UtxoResult

pub enum UtxoResult {
    Sync(Result<TxOut, UtxoLookupError>),
    Async(UtxoFuture),
}

The result of a UtxoLookup::get_utxo call. A call may resolve either synchronously, returning the Sync variant, or asynchronously, returning an UtxoFuture in the Async variant.

Variants

Sync(Result<TxOut, UtxoLookupError>)

A result which was resolved synchronously. It either includes a TxOut for the output requested or a UtxoLookupError.

Async(UtxoFuture)

A result which will be resolved asynchronously. It includes a UtxoFuture, a clone of which you must keep locally and call UtxoFuture::resolve on once the lookup completes.

Note that in order to avoid runaway memory usage, the number of parallel checks is limited, but only fairly loosely. Because a pending checks block all message processing, leaving checks pending for an extended time may cause DoS of other functions. It is recommended you keep a tight timeout on lookups, on the order of a few seconds.
