Errors produced by Phase 10 tidy operations.

Variants

ColumnNotFound(String)

A column referenced in the expression was not found.

DuplicateColumn(String)

A duplicate column name was supplied in select/mutate.

PredicateNotBool

The filter predicate evaluated to a non-boolean value.

Fields

got: String

TypeMismatch

A mutate expression produced a type mismatch.

Fields

expected: String

got: String

LengthMismatch

Scalar broadcast to a vector of non-matching length.

Fields

expected: usize

got: usize

Internal(String)

An internal/unexpected error (wraps DataError strings).

EmptyGroup

first() or last() called on an empty group.

CapacityExceeded

Phase 17: too many distinct levels for a u16 FctColumn.

Fields

limit: usize

got: usize

Implementations

impl TidyError

pub fn schema_mismatch(msg: impl Into<String>) -> Self

Construct a schema mismatch error.

pub fn join_type_mismatch(col: &str, lt: &str, rt: &str) -> Self

Construct a type mismatch for join validation.

pub fn duplicate_key(key: impl Into<String>) -> Self

Duplicate join/pivot key error.

pub fn empty_selection(msg: impl Into<String>) -> Self

Empty selection (e.g. pivot_longer with zero value_cols).

impl TidyError

pub fn capacity_exceeded(limit: usize, got: usize) -> Self

Convenience constructor for a capacity-exceeded error.

Trait Implementations

impl Clone for TidyError

fn clone(&self) -> TidyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TidyError

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

Formats the value using the given formatter.

impl Display for TidyError

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

Formats the value using the given formatter.

impl Error for TidyError

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 TidyError

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