Errors encountered while converting between logical schema representations.

Variants

UnsupportedLogicalType

The logical type is not supported by the target representation.

Fields

column: String

Column name that failed conversion.

type_name: String

High-level type name (for diagnostics).

details: String

Additional details describing why it is unsupported.

FixedBinaryInvalidWidth

FixedBinary fields must declare a positive byte width.

Fields

column: String

Column name that failed validation.

byte_width: i32

Declared byte width.

Int96Unsupported

Int96 is rejected for now to avoid legacy timestamp ambiguity.

Fields

column: String

Column name that failed conversion.

OtherTypeUnsupported

Catch-all “Other” types are not accepted in v0.1.

Fields

column: String

Column name that failed conversion.

name: String

Type name reported by the source.

DecimalInvalid

Decimal precision/scale is out of supported bounds for Arrow conversion.

Fields

column: String

Column name that failed conversion.

precision: i32

Declared total precision.

scale: i32

Declared scale (digits to the right of the decimal point).

details: String

Human-readable details describing the constraint violation.

MapKeyMustBeNonNull

Map keys must be non-nullable when converting to Arrow.

Fields

column: String

Column name that failed conversion.

Trait Implementations

impl Debug for SchemaConvertError

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

Formats the value using the given formatter.

impl Display for SchemaConvertError

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

Formats the value using the given formatter.

impl Error for SchemaConvertError

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 SchemaConvertError

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<SchemaConvertError> for TableMetaSchemaError

fn from(error: SchemaConvertError) -> Self

Converts to this type from the input type.
