Expand description

Interpreter runtime error variants.

Variants

`PanicInstruction(InstructionResult)`

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

`Panic(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)`

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)`

I/O and OS related errors.

Implementations

source

impl InterpreterError

source

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

Describe the error as recoverable or halt.

source

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

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

source

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

Return the instruction that caused this error, if applicable.

source

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

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

source

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

Produces a halt error from io.

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
