Variants

EmptyRecordKey

Record keys must be nonempty.

DuplicateRecordKey

Keys must be globally unique across shards.

ZeroLimit

A page must request at least one row.

ResultLimitExceeded

Requested page size exceeds policy.

Fields

requested: usize

Requested page size.

maximum: usize

Configured maximum.

FilterNodesExceeded

Filter expression is too large.

Fields

actual: usize

Observed filter nodes.

maximum: usize

Configured maximum.

FilterDepthExceeded

Filter recursion is too deep.

Fields

actual: usize

maximum: usize

Configured maximum.

SortFieldsExceeded

Too many explicit sort fields were requested.

Fields

actual: usize

Requested fields.

maximum: usize

CursorShape

Cursor shape does not match the sort plan.

Fields

actual: usize

Cursor values.

expected: usize

Query sort fields.

EmptyCursorKey

Cursor keys must be nonempty.

NoncanonicalCursorNull

Explicit null must use the canonical None cursor representation.

InvalidPrefixType

A prefix filter literal is not a string or bytes value.

InvalidFieldPath

Field-path segments must be nonempty UTF-8 strings.

GroupFieldsExceeded

Too many group fields were requested.

Fields

actual: usize

Requested group fields.

maximum: usize

Configured maximum.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Eq for QueryError

impl Error for QueryError

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 PartialEq for QueryError

fn eq(&self, other: &QueryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
