Machine-readable diagnostic code.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedArrowType

An Arrow type is not supported by the selected operation.

LossyConversionRequiresPolicy

A conversion may lose information and requires explicit policy.

PolicyApplied

An explicit conversion policy was applied.

IdentifierInvalid

A SQL Server identifier is invalid.

IdentifierTooLong

A SQL Server identifier exceeds the supported length.

DecimalOutOfRange

A decimal value, precision, or scale is outside the supported range.

IntegerOutOfRange

An integer value is outside the supported range.

TimestampOutOfRange

A timestamp value is outside the supported range.

TimezoneUnsupported

A timestamp timezone cannot be mapped to a deterministic SQL Server value.

This is used for invalid timezone names, invalid fixed offset strings, and resolved offsets SQL Server cannot represent.

SchemaMismatch

A runtime batch schema does not match the planned schema.

BackendUnavailable

A requested write backend is unavailable.

ProfileDependentConversion

A mapping depends on explicit user policy.

ObservedDataRequired

A selected policy needs observed values or statistics, not just schema.

ValueConversionUnsupported

A planned value conversion is not supported by the current converter.

ValueTypeMismatch

A runtime value or array type does not match the planned conversion.

NullInNonNullableColumn

A runtime null value was found for a non-nullable target column.

NonFiniteFloat

A floating-point value is not finite.

ValueTooLong

A runtime value exceeds the planned target type length.

RowIndexOutOfBounds

A requested row index is outside the runtime batch.

DirectEncodingInvalidPayload

Direct raw TDS encoding produced or received invalid payload state.

DirectEncodingUnsupportedMapping

A planned mapping is not supported by the direct raw TDS encoder.

DirectEncodingUnsupportedBatch

Runtime batch shape is not supported by the current direct raw TDS encoder.

Trait Implementations

impl Clone for DiagnosticCode

fn clone(&self) -> DiagnosticCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticCode

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

Formats the value using the given formatter.

impl Hash for DiagnosticCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DiagnosticCode

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