Errors that can occur while validating or decoding segment metadata.

This enum intentionally contains no storage backend errors. IO-related errors should be wrapped at the IO boundary (for example, in crate::transaction_log::SegmentError).

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.

InvalidIndexBounds

Persisted segment bounds violate the table’s ordered-index domain.

Fields

path: String

Segment path containing invalid bounds.

source: IndexValueError

Domain or ordering failure.

TooShort

The file is too short to be a valid Parquet file.

Fields

path: String

The path to the file that was too short.

ParquetRead

Parquet reader / metadata failure.

Fields

path: String

The path to the file that caused the Parquet read failure.

source: ParquetError

Underlying parquet error that caused this failure.

backtrace: Backtrace

Diagnostic backtrace for this error.

RowGroupTask

A parallel row-group inspection task failed before returning its typed result.

Fields

path: String

Segment path being inspected.

source: JoinError

Tokio task failure, including panic or cancellation details.

backtrace: Backtrace

Backtrace captured while joining the row-group task.

OrderedIndexColumn

The registered ordered-index column is missing or incompatible.

Fields

source: ParquetIndexColumnError

Exact registered and observed Parquet column details.

ParquetStatsShape

Statistics exist but are not well-shaped (wrong length / unexpected type).

Fields

path: String

The path to the file with malformed Parquet statistics.

column: String

The column whose statistics are malformed.

detail: String

Details about how the statistics are malformed.

NoObservedIndexValue

The file contains no non-null value for the registered ordered index.

Fields

path: String

Path to the segment file.

column: String

Registered ordered-index column.

expected_domain: &'static str

Registered ordered-index domain.

LogicalSchemaInvalid

Failed to derive a valid LogicalSchema from the Parquet file.

Fields

path: String

The path to the file without a valid LogicalSchema.

source: Box<LogicalSchemaValidationError>

Underlying logical schema error that triggered this failure.

backtrace: Backtrace

Backtrace captured with segment path context.

ArrowToLogicalSchema

An embedded Arrow schema cannot be represented by the logical schema model.

Fields

path: String

Segment path containing the embedded Arrow schema.

source: Box<ArrowToLogicalSchemaError>

Exact Arrow-to-logical conversion failure.

backtrace: Backtrace

Backtrace captured with segment path context.

Trait Implementations

impl Debug for SegmentMetaError

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

Formats the value using the given formatter.

impl Display for SegmentMetaError

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

Formats the value using the given formatter.

impl Error for SegmentMetaError

where Self: Debug + Display,

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.

impl ErrorCompat for SegmentMetaError

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<ParquetIndexColumnError> for SegmentMetaError

where ParquetIndexColumnError: Into<ParquetIndexColumnError>,

fn from(error: ParquetIndexColumnError) -> Self

Converts to this type from the input type.

impl From<SegmentMetaError> for SegmentError

where SegmentMetaError: Into<SegmentMetaError>,

fn from(error: SegmentMetaError) -> Self

Converts to this type from the input type.
