Errors detected during structural validation of a deserialized plan.

Variants

InvalidRootOp

root_op index is out of bounds.

Fields

root_op: u32

num_ops: u32

InputOutOfBounds

An op at op_index references an input that is out of bounds.

Fields

op_index: u32

field: &'static str

input: u32

num_ops: u32

ForwardReference

An op at op_index references a forward (or self) input, which would create a cycle or depend on an op that hasn’t been computed yet.

Fields

op_index: u32

field: &'static str

input: u32

EmptyPlan

The plan contains no ops.

ExprColOutOfBounds

An op has a column index reference outside the available input width.

Fields

op_index: u32

field: &'static str

col_idx: u32

input_width: u32

ColumnIndexOutOfBounds

An op references a key/column index outside the available input width.

Fields

op_index: u32

field: &'static str

col_idx: u32

input_width: u32

SchemaArityMismatch

A schema-bearing op has inconsistent arity contracts.

Fields

op_index: u32

field: &'static str

expected: u32

actual: u32

SortArityMismatch

Sort key and sort direction vectors differ in length.

Fields

op_index: u32

keys: u32

dirs: u32

InvalidGraphRef

A graph_ref on a graph-touching op is malformed.

Fields

op_index: u32

field: &'static str

value: String

NonPositiveValue

A field requiring a strictly positive integer received zero.

Fields

op_index: u32

field: &'static str

value: u32

SchemaKindMismatch

A column referenced by a field has the wrong ColKind for the op.

Fields

op_index: u32

field: &'static str

col_idx: u32

expected_kind: ColKind

actual_kind: ColKind

Trait Implementations

impl Clone for PlanValidationError

fn clone(&self) -> PlanValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlanValidationError

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

Formats the value using the given formatter.

impl Display for PlanValidationError

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

Formats the value using the given formatter.

impl Error for PlanValidationError

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 PlanValidationError

fn eq(&self, other: &PlanValidationError) -> 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.
