Wrapper of bitcoincore_rpc Error.

NoFeature

Returned when calling methods requiring a feature to be activated, but it’s not.

NoEnvVar

Returned when calling methods requiring a env var to exist, but it’s not.

NoBitcoindExecutableFound

EarlyExit(ExitStatus)

Wrapper of early exit status.

BothDirsSpecified

Returned when both tmpdir and staticdir is specified in Conf options.

RpcUserAndPasswordUsed
