Errors from table coverage queries and read-only coverage recovery.

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.

InvalidRange

The requested half-open ordered-index range is invalid.

Fields

source: IndexValueError

Complete range validation error.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

IndexIntervalMapping

An ordered value could not be mapped to its index interval ID.

Fields

source: IndexIntervalMappingError

Complete interval mapping error.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

InvalidEntityIdentity

Constructing a canonical entity identity failed.

Fields

source: EntityIdentityError

Complete entity identity construction error.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

SchemaCompatibility

The query identity is incompatible with the table schema.

Fields

source: Box<SchemaCompatibilityError>

Complete schema compatibility error.

EntityIdentityRequired

An identity-free query was used on an entity-aware table.

Fields

entity_columns: Vec<String>

Entity columns that require values from the caller.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

EntityIdentityNotConfigured

An entity-aware query was used on a table with global coverage.

Fields

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

MissingEntityIdentityColumn

A required entity column has no caller-provided value.

Fields

column: String

Configured entity column missing from the caller input.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

DuplicateEntityIdentityColumn

Caller input repeats one entity column.

Fields

column: String

Repeated entity column name.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

UnexpectedEntityIdentityColumn

Caller input contains a column outside the entity identity.

Fields

column: String

Unknown entity column name.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

CoverageSnapshotRead

Reading a table coverage snapshot sidecar failed.

Fields

coverage_path: String

Table-relative sidecar path.

source: Box<CoverageSidecarError>

Complete sidecar error, including storage or codec detail.

ExistingSegmentMissingCoverageMetadata

An existing segment has no coverage sidecar path.

Fields

segment_path: String

Canonical segment path missing a coverage path.

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

SegmentCoverageSidecarRead

Reading a segment sidecar failed during read-only recovery.

Fields

segment_path: String

Canonical segment path.

coverage_path: String

Table-relative sidecar path.

source: Box<CoverageSidecarError>

Complete sidecar error, including storage or codec detail.

MissingTableCoveragePointer

Table state has segments but no coverage snapshot pointer.

Fields

backtrace: Box<Backtrace>

Backtrace captured at the coverage query boundary.

Trait Implementations

impl Debug for CoverageQueryError

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

Formats the value using the given formatter.

impl Display for CoverageQueryError

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

Formats the value using the given formatter.

impl Error for CoverageQueryError

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 CoverageQueryError

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.
