Enum JoinPlanError 

#[non_exhaustive]
pub enum JoinPlanError {
    UnsupportedJoinType {
        join_type: JoinType,
    },
    UnsupportedJoinConstraint {
        constraint: JoinConstraint,
    },
    UnsupportedPredicate {
        left: String,
        right: String,
    },
}

Errors encountered while converting a join logical plan.

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.

UnsupportedJoinType

Only inner joins can be converted to the current proof plan.

Fields

join_type: JoinType

Unsupported join type.

UnsupportedJoinConstraint

Only ON join constraints can be converted to the current proof plan.

Fields

constraint: JoinConstraint

Unsupported join constraint.

UnsupportedPredicate

The join predicate is not a supported pair of matching column references.

Fields

left: String

Left-hand join expression.

right: String

Right-hand join expression.

Trait Implementations

impl Clone for JoinPlanError

fn clone(&self) -> JoinPlanError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinPlanError

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

Formats the value using the given formatter.

impl Eq for JoinPlanError

impl Error for JoinPlanError

where Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 ErrorCompat for JoinPlanError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<JoinPlanError> for PlannerError

fn from(error: JoinPlanError) -> Self

Converts to this type from the input type.

impl PartialEq for JoinPlanError

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

Equality operator ==.

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

Inequality operator !=.
