Errors that can occur during segment operations.

Variants

CorruptFile

The segment file is corrupt or has an invalid format.

Fields

detail: String

Human-readable description of the corruption.

InvalidMagic

Invalid magic bytes in header or footer.

ChecksumMismatch

CRC32c checksum mismatch.

Fields

expected: u32

Expected checksum value.

actual: u32

Actual computed checksum.

UnsupportedVersion

Unsupported segment version.

Fields

version: u16

The version number found in the file.

Io(Error)

An I/O error occurred.

Encoding(EncodingError)

An encoding error occurred.

AlreadyFinalized

The segment writer has already been finalized.

EmptySegment

No data has been written to the segment.

RowGroupOutOfRange

Row group index is out of range.

Fields

index: usize

Trait Implementations

impl Debug for SegmentError

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

Formats the value using the given formatter.

impl Display for SegmentError

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

Formats the value using the given formatter.

impl Error for SegmentError

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.
