Enum PlanError 

pub enum PlanError {
    UnknownColumn(ColumnId),
    TypeMismatch {
        column: ColumnId,
        expected: ColumnType,
        actual: ColumnType,
    },
    RangeRequiresNumericColumn(ColumnId),
    RowCountMismatch {
        columns: u32,
        alive: u32,
    },
}

A typed planning-time predicate rejection.

Variants

UnknownColumn(ColumnId)

The predicate named a column absent from the collection schema.

TypeMismatch

A predicate value disagreed with its declared column type.

Fields

column: ColumnId

Mismatched column.

expected: ColumnType

Declared type.

actual: ColumnType

Supplied type.

RangeRequiresNumericColumn(ColumnId)

A range was attached to a non-numeric column.

RowCountMismatch

Metadata and alive arrays described different row spaces.

Fields

columns: u32

Metadata row count.

alive: u32

Alive row count.

Trait Implementations

impl Clone for PlanError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlanError

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

Formats the value using the given formatter.

impl Display for PlanError

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

Formats the value using the given formatter.

impl Eq for PlanError

impl Error for PlanError

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<PlanError> for FilteredSearchError

fn from(error: PlanError) -> Self

Converts to this type from the input type.

impl PartialEq for PlanError

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

Equality operator ==.

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

Inequality operator !=.
