Implementations

impl ConversionError

pub fn non_numeric_expr_in_agg<S: Into<String>>(dtype: S, func: S) -> Self

Returns a ConversionError::InvalidExpression for non-numeric types used in numeric aggregation functions.

Trait Implementations

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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 ConversionError

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 ConversionError

fn from(error: ColumnOperationError) -> Self

Converts to this type from the input type.

impl From<ConversionError> for String

fn from(error: ConversionError) -> Self

Converts to this type from the input type.

impl From<DecimalError> for ConversionError

fn from(error: DecimalError) -> Self

Converts to this type from the input type.

impl From<IntermediateDecimalError> for ConversionError

fn from(err: IntermediateDecimalError) -> ConversionError

Converts to this type from the input type.

impl From<PoSQLTimestampError> for ConversionError

fn from(error: PoSQLTimestampError) -> Self

Converts to this type from the input type.

impl From<PostprocessingError> for ConversionError

fn from(error: PostprocessingError) -> Self

Converts to this type from the input type.

impl From<String> for ConversionError

fn from(value: String) -> Self

impl PartialEq for ConversionError

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