Error type for the SDK

Variants

Config(String)

SDK is not configured properly

Drive(Error)

Drive error

DriveProofError(ProofError, Vec<u8>, BlockInfo)

Drive proof error with associated proof bytes and block info

Protocol(ProtocolError)

DPP error

Proof(Error)

Proof verification error

InvalidProvedResponse(String)

Invalid Proved Response error

DapiClientError(DapiClientError)

DAPI client error, for example, connection error

DapiMocksError(MockError)

DAPI mocks error

CoreError(Error)

Dash core error

MerkleBlockError(MerkleBlockError)

MerkleBlockError

CoreClientError(Error)

Core client error, for example, connection error

MissingDependency(String, String)

Dependency not found, for example data contract for a document not found

TotalCreditsNotFound

Total credits in Platform are not found; we must always have credits in Platform

EpochNotFound

Epoch not found; we must have at least one epoch

TimeoutReached(Duration, String)

SDK operation timeout reached error

AlreadyExists(String)

Returned when an attempt is made to create an object that already exists in the system

InvalidCreditTransfer(String)

Invalid credit transfer configuration

NonceOverflow(u64)

Identity nonce overflow: the nonce has reached its maximum value and cannot be incremented further without wrapping to zero.

IdentityNonceNotFound(String)

Identity nonce not found on Platform.

Platform returned no nonce for the requested identity (or identity– contract pair). This usually means the queried DAPI node has not yet indexed the identity — for example right after identity creation or when the node is lagging behind the chain tip.

Recovery: retry the state transition; the SDK will re-fetch the nonce from a (potentially different) DAPI node on the next attempt.

Generic(String)

Generic error

ContextProviderError(ContextProviderError)

Context provider error

Cancelled(String)

Operation cancelled - cancel token was triggered, timeout, etc.

StaleNode(StaleNodeError)

Remote node is stale; try another server

StateTransitionBroadcastError(StateTransitionBroadcastError)

Error returned when trying to broadcast a state transition

NoAvailableAddressesToRetry(Box<Error>)

All available addresses have been exhausted (banned due to errors). Contains the last meaningful error that caused addresses to be banned.

Trait Implementations

impl CanRetry for Error

fn can_retry(&self) -> bool

Returns true if the operation can be retried safely.

fn is_no_available_addresses(&self) -> bool

Returns true if this error represents a “no available addresses” condition.

fn is_node_failure(&self) -> bool

👎Deprecated: Use !can_retry() instead

Get boolean flag that indicates if the error is retryable.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
