Variants (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.

Network(String, Error)

failed to connect to network.

ObjectLookup(String)

could not lookup an object ID.

MigrationRegistryNotFound(Error)

MigrationRegistry error.

DIDResolutionError(String)

Caused by a look failures during resolution.

InvalidArgument(String)

Caused by invalid or missing arguments.

InvalidKey(String)

Caused by invalid keys.

GasIssue(String)

Caused by issues with paying for transaction.

ParsingFailed(String)

Could not parse module, package, etc.

TransactionBuildingFailed(String)

Could not build transaction.

TransactionSigningFailed(String)

Could not sign transaction.

TransactionExecutionFailed(Error)

Could not execute transaction.

TransactionUnexpectedResponse(String)

Transaction yielded invalid response. This usually means that the transaction was executed but did not produce the expected result.

TransactionOffChainApplicationFailure

A transaction was successfully executed on the ledger, but its off-chain logic couldn’t be applied.

Fields

source: Box<Error>

The actual error coming from apply.

response: Box<IotaTransactionBlockResponse>

The raw RPC response, as received by the client.

InvalidConfig(String)

Config is invalid.

DidDocParsingFailed(String)

Failed to parse DID document.

DidDocSerialization(String)

Failed to serialize DID document.

Identity(String)

Identity related error.

InvalidIdentityHistory(String)

Unexpected state when looking up identity history.

MissingPermission(String)

An operation cannot be carried on for a lack of permissions - e.g. missing capability.

RpcError(String)

An error caused by either a connection issue or an invalid RPC call.

BcsError(Error)

An error caused by a bcs serialization or deserialization.

AnyError(Error)

An anyhow::error.

FfiError(String)

An error caused by a foreign function interface call.

IotaInteractionError(Error)

Caused by an interaction with the IOTA protocol.

IotaInteractionAdapterError(Error)

Caused by a platform-specific adapter to interact with the IOTA protocol.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
