Enum mz_pgrepr::TypeConversionError

pub enum TypeConversionError {
    UnsupportedType(Type),
    InvalidNumericMaxScale(InvalidNumericMaxScaleError),
    InvalidNumericConstraint(String),
    InvalidCharLength(InvalidCharLengthError),
    InvalidVarCharMaxLength(InvalidVarCharMaxLengthError),
    InvalidTimestampPrecision(InvalidTimestampPrecisionError),
}

An error that can occur when converting a Type to a ScalarType.

Variants

UnsupportedType(Type)

The source type is unsupported as a ScalarType.

InvalidNumericMaxScale(InvalidNumericMaxScaleError)

The source type contained an invalid max scale for a ScalarType::Numeric.

InvalidNumericConstraint(String)

The source type contained an invalid constraint for a ScalarType::Numeric.

InvalidCharLength(InvalidCharLengthError)

The source type contained an invalid length for a ScalarType::Char.

InvalidVarCharMaxLength(InvalidVarCharMaxLengthError)

The source type contained an invalid max length for a ScalarType::VarChar.

InvalidTimestampPrecision(InvalidTimestampPrecisionError)

The source type contained an invalid precision for a ScalarType::Timestamp or ScalarType::TimestampTz.

Trait Implementations

impl Clone for TypeConversionError

fn clone(&self) -> TypeConversionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeConversionError

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

Formats the value using the given formatter.

impl Display for TypeConversionError

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

Formats the value using the given formatter.

impl Error for TypeConversionError

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.
