The errors that can happen while executing the VM

Variants

InvalidArguments

Invalid arguments in host call

ContractPanic(String)

The contract panicked with message in String

MemoryNotFound

Could not find WASM memory

InstrumentationError(InstrumentationError)

Error during the instrumentalization

InvalidABICall

Invalid ABI Call

InvalidUtf8

Invalid Utf8

InvalidEd25519PublicKey

Invalid Public key

InvalidEd25519Signature

Invalid Signature

ContractReturn(i32, i32)

Contract returned, not an error per se, this is how contracts return.

OutOfGas

Contract execution ran out of gas

NotEnoughFunds

Not enough funds for call

UnknownContract

Contract could not be found in the state

WASMError(Error)

WASM threw an error

IOError(Error)

Input output error

InvalidWASMModule

Invalid WASM Module

StoreError(CanonError)

Error propagated from underlying store

PersistenceSerializationError(CanonError)

Serialization error from the state persistence mechanism

PersistenceError(String)

Other error from the state persistence mechanism

WasmerExportError(ExportError)

WASMER export error

WasmerRuntimeError(RuntimeError)

WASMER runtime error

WasmerCompileError(CompileError)

WASMER compile error

Implementations

impl VMError

pub fn from_store_error(err: CanonError) -> Self

Create a VMError from the associated stores

Trait Implementations

impl Debug for VMError

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

Formats the value using the given formatter.

impl Display for VMError

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

Formats the value using the given formatter.

impl Error for VMError

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.
