Errors raised by the parametric validators.

Variants

VarcharOverflow

Input string exceeds VARCHAR’s declared max_len.

Fields

actual: usize

max: u32

DecimalPrecisionOverflow

Decimal exceeds declared total precision.

Fields

precision: u8

actual_digits: usize

DecimalScaleOverflow

Decimal scale doesn’t match the declared scale (rounded would lose information).

Fields

scale: u8

actual_fraction_digits: usize

NotADecimal(String)

Input is not a parsable decimal at all.

BadModifier(String)

SqlTypeName modifier list doesn’t match the expected shape for VARCHAR(n) / DECIMAL(p,s).

Trait Implementations

impl Clone for ParametricError

fn clone(&self) -> ParametricError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParametricError

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

Formats the value using the given formatter.

impl Display for ParametricError

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

Formats the value using the given formatter.

impl Error for ParametricError

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.
