Enum fuel_vm::error::InterpreterError

pub enum InterpreterError {
    PanicInstruction(InstructionResult),
    Panic(PanicReason),
    ValidationError(ValidationError),
    PredicateFailure,
    NoTransactionInitialized,
    Io(Error),
}

Interpreter runtime error variants.

Variants

PanicInstruction(InstructionResult)

Tuple Fields

0: InstructionResult

The instructions execution resulted in a well-formed panic, caused by an explicit instruction.

Panic(PanicReason)

Tuple Fields

0: PanicReason

The VM execution resulted in a well-formed panic. This panic wasn’t caused by an instruction contained in the transaction or a called contract.

ValidationError(ValidationError)

Tuple Fields

0: ValidationError

The provided transaction isn’t valid.

PredicateFailure

The predicate verification failed.

NoTransactionInitialized

No transaction was initialized in the interpreter. It cannot provide state transitions.

Io(Error)

Tuple Fields

0: Error

I/O and OS related errors.

Implementations

impl InterpreterError

pub fn from_runtime(error: RuntimeError, instruction: Instruction) -> Self

Describe the error as recoverable or halt.

pub const fn panic_reason(&self) -> Option<PanicReason>

Return the specified panic reason that caused this error, if applicable.

pub const fn instruction(&self) -> Option<&Instruction>

Return the instruction that caused this error, if applicable.

pub fn instruction_result(&self) -> Option<&InstructionResult>

Return the underlying InstructionResult if this instance is PanicInstruction; returns None otherwise.

pub fn from_io<E>(e: E) -> Self where
    E: Into<Error>, 

Produces a halt error from io.

Trait Implementations

impl Debug for InterpreterError

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

Formats the value using the given formatter.

impl Display for InterpreterError

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

Formats the value using the given formatter.

impl Error for InterpreterError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
