Represents any possible error from a fallible function in the Hiero SDK.

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.

TimedOut(Box<Error>)

Request timed out.

GrpcStatus(Status)

GRPC status code was an error.

FromProtobuf(Box<dyn StdError + Send + Sync + 'static>)

Failed to parse an SDK type from a protobuf response.

FreezeUnsetNodeAccountIds

Freeze failed due to there being no explicitly set node account IDs and no client being provided to generate them.

TransactionPreCheckStatus

A transaction failed pre-check.

The transaction had the ID transaction_id.

Caused by status being an error.

Fields

status: Status

The status that caused the Transaction to fail pre-check.

transaction_id: Box<TransactionId>

The TransactionId of the failed Transaction .

cost: Option<Hbar>

The estimated transaction fee, if the status was [InsufficientTxFee].

QueryPreCheckStatus

A Query for transaction_id failed pre-check.

Caused by status being an error.

Fields

status: Status

The Status that caused the Query to fail pre-check.

transaction_id: Box<TransactionId>

The associated transaction’s ID.

QueryPaymentPreCheckStatus

A Query failed pre-check.

The query had an associated PaymentTransaction with ID transaction_id.

Caused by status being an error.

Fields

status: Status

The Status that caused the Query to fail pre-check.

transaction_id: Box<TransactionId>

The associated PaymentTransaction’s TransactionId.

QueryNoPaymentPreCheckStatus

A Query failed pre-check.

The query had no PaymentTransaction.

Caused by status being an error.

Fields

status: Status

The Status that caused the Query to fail pre-check.

BasicParse(Box<dyn StdError + Send + Sync + 'static>)

Failed to parse a basic type from string (ex. AccountId, ContractId, TransactionId, etc.).

BadEntityId

An entity ID had an invalid checksum

Fields

shard: u64

The shard number

realm: u64

The realm number

num: u64

The entity number

present_checksum: Checksum

The (invalid) checksum that was present on the entity ID

expected_checksum: Checksum

The checksum that SHOULD HAVE BEEN on the entity ID

CannotCreateChecksum

An entity ID cannot be converted to a string with a checksum, because it is in an alternate form, such as an alias or evm_address

KeyParse(Box<dyn StdError + Send + Sync + 'static>)

Failed to parse a PublicKey or PrivateKey.

KeyDerive(Box<dyn StdError + Send + Sync + 'static>)

Failed to derive a PrivateKey from another PrivateKey.

Examples of when this can happen (non-exhaustive):

• PrivateKey::derive when the PrivateKey doesn’t have a chain code.
• PrivateKey::derive or PrivateKey::legacy_derive on an Ecsda key.

MnemonicParse

Failed to parse a Mnemonic due to the given reason.

the Mnemonic is provided because invalid Mnemonics can technically still provide valid PrivateKeys.

Fields

reason: MnemonicParseError

This error’s source.

mnemonic: Mnemonic

The Mnemonic in question.

MnemonicEntropy(MnemonicEntropyError)

An error occurred while attempting to convert a Mnemonic to a PrivateKey

NoPayerAccountOrTransactionId

The Client had no payer account (operator) and the attempted request had no explicit TransactionId.

MaxQueryPaymentExceeded

Cost of a Query is more expensive than max_query_payment.

The actual cost of the Query is query_cost.

Fields

max_query_payment: Hbar

the configured maximum query payment.

query_cost: Hbar

How much the query actually cost.

NodeAccountUnknown(Box<AccountId>)

The associated node account was not found in the network.

ResponseStatusUnrecognized(i32)

Received an unrecognized status code from the Hiero Network.

This can happen when the SDK is outdated, try updating your SDK.

ReceiptStatus

Getting the receipt for transaction_id failed with status.

Fields

status: Status

The Error’s status code.

transaction_id: Option<Box<TransactionId>>

The Transaction’s ID.

SignatureVerify(Box<dyn StdError + Send + Sync + 'static>)

Failed to verify a signature.

Trait Implementations

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

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.

impl From<MnemonicEntropyError> for Error

fn from(source: MnemonicEntropyError) -> Self

Converts to this type from the input type.

impl From<Status> for Error

fn from(source: Status) -> Self

Converts to this type from the input type.
