Trait Implementations

impl Debug for ExpressionEvaluationError

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

Formats the value using the given formatter.

impl Display for ExpressionEvaluationError

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

Formats the value using the given formatter.

impl Error for ExpressionEvaluationError

where Self: Debug + Display,

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

Returns the lower-level source of this error, if any.

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 ErrorCompat for ExpressionEvaluationError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<ColumnOperationError> for ExpressionEvaluationError

fn from(error: ColumnOperationError) -> Self

Converts to this type from the input type.

impl From<DecimalError> for ExpressionEvaluationError

fn from(error: DecimalError) -> Self

Converts to this type from the input type.

impl From<ExpressionEvaluationError> for PostprocessingError

fn from(error: ExpressionEvaluationError) -> Self

Converts to this type from the input type.

impl PartialEq for ExpressionEvaluationError

fn eq(&self, other: &ExpressionEvaluationError) -> 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.
