Enum ExpressionError 

pub enum ExpressionError {
    InvalidMleIndex,
    EvaluationError(&'static str),
    MleError(MleError),
    SelectorBitNotBoundError,
    EvaluateNotFullyBoundError,
    EvaluateNotFullyIndexedError,
    EvaluateBoundIndicesDontMatch,
    TranscriptError(TranscriptReaderError),
}

Error for handling the parsing and evaluation of expressions.

Variants

InvalidMleIndex

Error for when an InvalidMleIndex is found while evaluating an expression TODO!(add some diagnoistics here)

EvaluationError(&'static str)

Error for when something unlikely goes wrong while evaluating an expression TODO!(split this up into many error variants)

MleError(MleError)

Error that wraps an MleError.

SelectorBitNotBoundError

Selector bit not bound before final evaluation gather.

EvaluateNotFullyBoundError

MLE ref with more than one element in its bookkeeping table.

EvaluateNotFullyIndexedError

During evaluation, an MLE should not contain crate::mle::MleIndex::Free variables.

EvaluateBoundIndicesDontMatch

The bound indices of this expression don’t match the indices passed in.

TranscriptError(TranscriptReaderError)

Transcript Reader Error.

Trait Implementations

impl Clone for ExpressionError

fn clone(&self) -> ExpressionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionError

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

Formats the value using the given formatter.

impl Display for ExpressionError

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

Formats the value using the given formatter.

impl Error for ExpressionError

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 From<ExpressionError> for LayerError

fn from(source: ExpressionError) -> Self

Converts to this type from the input type.

impl From<MleError> for ExpressionError

fn from(source: MleError) -> Self

Converts to this type from the input type.

impl From<TranscriptReaderError> for ExpressionError

fn from(source: TranscriptReaderError) -> Self

Converts to this type from the input type.

impl PartialEq for ExpressionError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
