Enum OperandFault 

pub enum OperandFault {
    NonCanonicalShift,
    ShiftAmountTooLarge {
        shift_amount: usize,
        max_amount: usize,
    },
    NonCanonicalShiftSequence,
    CollapsibleShiftSequence {
        composition: Composition,
    },
    ScratchValueIndex,
    OutOfRangeValueIndex {
        segment: ValueSegment,
        value_index: u32,
        segment_len: usize,
    },
}

The way one term of an operand is malformed, said without naming where the operand sits.

A diagnostic pairs this with the position of the operand it checked, which differs between a constraint and a chip call.

Trait Implementations

impl Debug for OperandFault

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

Formats the value using the given formatter.

impl Display for OperandFault

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

Formats the value using the given formatter.

impl Error for OperandFault

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.
