Struct LocalRpcCommitSource 

pub struct LocalRpcCommitSource { /* private fields */ }

Optional local Litecoin Core: it may start, stop, restart or hang at any time. Holds only the URL and cookie path; every lookup and probe reads the cookie, and the chain and txindex are verified again whenever it changes. Every RPC is bounded (see rpc), so a stopped or hung Core costs a lookup at most its budget before the next source is tried.

Implementations

impl LocalRpcCommitSource

pub const PROBE_INTERVAL: Duration

pub const PROBE_BUDGET: Duration

Total time one probe may take, cookie verification included.

pub const FETCH_BUDGET: Duration

Total time one lookup may take, cookie verification included.

pub fn new(chain: Chain, rpc_url: String, cookie_file: PathBuf) -> Self

pub fn with_probe_interval(self, interval: Duration) -> Self

pub fn with_budgets(self, probe: Duration, fetch: Duration) -> Self

Trait Implementations

impl CommitSource for LocalRpcCommitSource

fn fetch( &self, txid: Txid, cancelled: &AtomicBool, ) -> Result<Option<Vec<u8>>, Error>

Code -5 is Core’s “no such mempool or blockchain transaction”: absent.

fn chain(&self) -> Chain

fn probe(&self) -> Option<Result<(), Error>>

A bounded liveness check, rate-limited by the source itself and run by the maintenance thread, never by status. None when no fresh check ran (or the source has none); otherwise its result.
