Enum InterpError 

pub enum InterpError {
    UnknownBlock(BlockId),
    MissingRegister(RegisterId),
    RegisterArityMismatch {
        expected: usize,
        found: usize,
    },
    UnsupportedOperation(String),
    Fatal(i64),
    Machine(String),
}

Why an interpreted execution unit stopped abnormally.

Variants

UnknownBlock(BlockId)

Terminator targeted a block that does not exist in the unit.

MissingRegister(RegisterId)

An instruction read a register that was never written.

RegisterArityMismatch

A jump supplied a different number of arguments than the target block declares parameters.

Fields

expected: usize

found: usize

UnsupportedOperation(String)

The instruction uses an operator the interpreter does not implement yet. This fails loudly instead of producing wrong simulation results.

Fatal(i64)

The unit terminated with SIRTerminator::Error.

Machine(String)

The InterpMachine reported a failure.

Trait Implementations

impl Clone for InterpError

fn clone(&self) -> InterpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InterpError

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

Formats the value using the given formatter.

impl Display for InterpError

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

Formats the value using the given formatter.

impl Eq for InterpError

impl Error for InterpError

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 PartialEq for InterpError

fn eq(&self, other: &InterpError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
