Errors during compound ORDER BY resolution.

Variants

ColumnNotFound

The referenced column name was not found in any SELECT’s output aliases.

Fields

name: String

span: Span

IndexOutOfRange

A numeric column index is out of range (1-based in SQL, but converted).

Fields

index: usize

num_columns: usize

span: Span

IndexZeroOrNegative

A zero or negative numeric column index.

Fields

value: i64

span: Span

ExpressionNotAllowed

An expression (e.g. a+1) is not allowed in compound ORDER BY.

Fields

span: Span

Trait Implementations

impl Clone for CompoundOrderByError

fn clone(&self) -> CompoundOrderByError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompoundOrderByError

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

Formats the value using the given formatter.

impl Display for CompoundOrderByError

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

Formats the value using the given formatter.

impl Eq for CompoundOrderByError

impl Error for CompoundOrderByError

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 CompoundOrderByError

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