Why a query failed.

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.

Unsupported(String)

Unauthorized(String)

IndexNotFound(String)

ForkNotFound(String)

Backend(String)

TooLarge

The query asked for more than a single reply may carry: a limit above the page cap, or a result whose inline payloads exceed the LaserData Cloud’s reply-byte budget. what names the bound hit (“limit” / “reply bytes”), size is what was requested or reached, cap is the ceiling. Page with limit/offset (or drop the payload request) rather than retrying unchanged.

Fields

what: String

size: usize

cap: usize

Version

Fields

expected: u32

got: u32

Stale

A Consistency level could not be met within the managed deadline: the projector’s applied offset for the queried source sits at applied while the level required required. Fail-not-downgrade, so the caller retries (the projector is catching up) rather than unknowingly reading stale data. what names the source (index or partition) that lagged.

Fields

what: String

applied: u64

required: u64

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<'de> Deserialize<'de> for QueryError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for QueryError

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

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 From<&QueryError> for ErrorBody

fn from(error: &QueryError) -> Self

Converts to this type from the input type.

impl From<&QueryError> for ResultCode

fn from(error: &QueryError) -> Self

Converts to this type from the input type.

impl PartialEq for QueryError

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for QueryError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
