Engine state errors.

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.

RootNotFound(Digest)

Specified state root hash is not found.

InvalidProtocolVersion(ProtocolVersion)

Protocol version used in the deploy is invalid.

Genesis(Box<GenesisError>)

Genesis error.

WasmPreprocessing(PreprocessingError)

WASM preprocessing error.

WasmSerialization(SerializationError)

WASM serialization error.

Exec(Error)

Contract execution error.

Storage(Error)

Storage error.

Authorization

Authorization error.

InsufficientPayment

Payment code provided insufficient funds for execution.

GasConversionOverflow

Motes to gas conversion resulted in an overflow.

Deploy

General deploy error.

Finalization

Executing a payment finalization code resulted in an error.

Bytesrepr(String)

Serialization/deserialization error.

Mint(String)

Mint error.

InvalidKeyVariant

Invalid key variant.

ProtocolUpgrade(ProtocolUpgradeError)

Protocol upgrade error.

InvalidDeployItemVariant(String)

Invalid deploy item variant.

CommitError(CommitError)

Commit error.

MissingSystemContractRegistry

Missing system contract registry.

MissingSystemContractHash(String)

Missing system contract hash.

MissingChecksumRegistry

Missing checksum registry.

RuntimeStackOverflow

An attempt to push to the runtime stack while already at the maximum height.

FailedToGetWithdrawKeys

Failed to get the set of Key::Withdraw from global state.

FailedToGetStoredWithdraws

Failed to get the purses stored under Key::Withdraw

FailedToGetWithdrawPurses

Failed to convert the StoredValue into WithdrawPurse.

FailedToRetrieveUnbondingDelay

Failed to retrieve the unbonding delay from the auction state.

FailedToRetrieveEraId

Failed to retrieve the current EraId from the auction state.

MissingTrieNodeChildren(Vec<Digest>)

Failed to put a trie node into global state because some of its children were missing.

FailedToRetrieveAccumulationPurse

Failed to retrieve accumulation purse from handle payment system contract.

Implementations

impl Error

pub fn reverter(api_error: impl Into<ApiError>) -> Error

Creates an Error instance of an Error::Exec variant with an API error-compatible object.

This method should be used only by native code that has to mimic logic of a WASM executed code.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DataSize for Error

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

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)>

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.
