multi-query planning errors.

Variants

DuplicateQuery

Duplicate query id.

Fields

query: u32

Duplicate query id.

ZeroGraphHash

Query needs a non-zero graph hash.

Fields

query: u32

Invalid query id.

ZeroTraversalKey

Query needs a non-zero traversal compatibility key.

Fields

query: u32

Invalid query id.

ZeroGraphUploadBytes

Query must report non-zero resident graph upload bytes.

Fields

query: u32

Invalid query id.

GraphUploadBytesMismatch

Equal graph hashes must agree on the resident graph byte width.

Fields

graph_layout_hash: u64

Stable resident graph layout hash.

expected_bytes: u64

First byte width observed for this graph hash.

actual_bytes: u64

Conflicting byte width reported by this query.

query: u32

Query that reported the conflicting byte width.

ZeroBudget

Explicit device budget cannot be zero.

ByteCountOverflow

Byte arithmetic overflowed.

Fields

field: &'static str

Field being computed.

OverBudget

A grouped resident envelope exceeds the explicit device budget.

Fields

graph_layout_hash: u64

Group graph hash.

traversal_key: u64

Group traversal key.

required_bytes: u64

Required resident bytes.

budget_bytes: u64

Caller-provided budget.

StorageReserveFailed

Planner storage could not be reserved.

Fields

field: &'static str

Field being reserved.

requested: usize

Number of entries requested.

message: String

Allocator error text.

InternalInvariant

Planner state violated an internal construction invariant.

Fields

message: &'static str

Actionable invariant failure text.

Trait Implementations

impl Clone for MultiQueryExecutionError

fn clone(&self) -> MultiQueryExecutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiQueryExecutionError

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

Formats the value using the given formatter.

impl Display for MultiQueryExecutionError

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

Formats the value using the given formatter.

impl Eq for MultiQueryExecutionError

impl Error for MultiQueryExecutionError

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 MultiQueryExecutionError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
