Enum OptimizerError 

#[non_exhaustive]
pub enum OptimizerError {
    InvalidInput {
        optimizer: &'static str,
        source: PlanError,
    },
    InvalidRuleOutput {

    },
}

Errors produced while validating or executing optimizer rules.

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.

InvalidInput

The optimizer received a malformed input plan.

Fields

optimizer: &'static str

source: PlanError

InvalidRuleOutput

A rule returned a malformed output plan.

Fields

optimizer: &'static str

rule: String

source: PlanError

RulePanicked

A rule panicked while processing a plan.

Fields

optimizer: &'static str

rule: String

message: String

Trait Implementations

impl Clone for OptimizerError

fn clone(&self) -> OptimizerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizerError

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

Formats the value using the given formatter.

impl Display for OptimizerError

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

Formats the value using the given formatter.

impl Eq for OptimizerError

impl Error for OptimizerError

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 OptimizerError

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

Equality operator ==.

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

Inequality operator !=.
