Errors from data construction, lookup, or materialization.

Variants

LengthMismatch

Schema/data length mismatch.

Fields

expected: usize

Expected length.

actual: usize

Actual length.

context: &'static str

Context.

UnknownVariable

Unknown variable in this table.

Fields

id: VariableId

Requested id.

TypeMismatch

Column type does not match the requested view.

Fields

id: VariableId

Variable id.

expected: &'static str

Expected type label.

InvalidValidity

Invalid validity bitmap length.

Fields

message: &'static str

Explanation.

EmptySelection

Row selection produced an empty sample.

Fields

context: &'static str

Explanation.

IncompleteSeries

Temporal gather requires a complete series (no missing values or masked rows).

Fields

id: Option<VariableId>

Offending variable, when the gap is column-specific.

message: &'static str

Explanation.

InvalidArgument

Invalid argument (split policy, configuration, etc.).

Fields

message: String

Explanation.

Schema(String)

Underlying schema error.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> DataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Eq for DataError

impl Error for DataError

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 DataError

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

Equality operator ==.

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

Inequality operator !=.
