Errors from columnar segment encoding, decoding, and validation.

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.

Codec(CodecError)

TruncatedSegment

Fields

expected: usize

got: usize

InvalidMagic([u8; 4])

IncompatibleVersion

Fields

reader_major: u8

segment_major: u8

segment_minor: u8

FooterCrcMismatch

Fields

stored: u32

computed: u32

ColumnOutOfRange

Fields

index: usize

count: usize

SchemaMismatch

Fields

expected: usize

got: usize

EmptyMemtable

Serialization(String)

TypeMismatch

Fields

column: String

expected: String

NullViolation(String)

DuplicatePrimaryKey

PrimaryKeyNotFound

SegmentIdExhausted

Corruption

Structural corruption detected while parsing a segment header or footer.

offset is the byte position from the start of the segment where the problem was detected. segment_id is None when the parse fails before the id can be resolved (e.g. inside the footer itself).

Fields

segment_id: Option<String>

reason: String

offset: Option<u64>

MissingKek

Segment is encrypted (starts with SEGV) but no KEK was supplied.

KekRequired

Segment is plaintext (NDBS) but a KEK is configured (policy violation).

EncryptionFailed(String)

AES-256-GCM encryption of the segment payload failed.

DecryptionFailed(String)

AES-256-GCM decryption of the segment payload failed.

BudgetExhausted(MemError)

Memory budget exhausted or global ceiling exceeded.

Trait Implementations

impl Debug for ColumnarError

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

Formats the value using the given formatter.

impl Display for ColumnarError

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

Formats the value using the given formatter.

impl Error for ColumnarError

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 From<CodecError> for ColumnarError

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl From<MemError> for ColumnarError

fn from(source: MemError) -> Self

Converts to this type from the input type.
