Enum SingleTableProjectionError 

pub enum SingleTableProjectionError {
    NotSelectCore,
    MissingFromClause,
    UnsupportedFromSource,
    UnknownTableQualifier {
        qualifier: String,
    },
    ColumnNotFound {
        column: String,
    },
}

Errors during single-table result-column resolution.

Variants

NotSelectCore

The core is VALUES, not SELECT.

MissingFromClause

A FROM clause is required for table-backed projection resolution.

UnsupportedFromSource

Unsupported source shape (non-table source or joins present).

UnknownTableQualifier

A table qualifier did not match the single table or its alias.

Fields

qualifier: String

ColumnNotFound

A referenced column does not exist on the table.

Fields

column: String

Trait Implementations

impl Clone for SingleTableProjectionError

fn clone(&self) -> SingleTableProjectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SingleTableProjectionError

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

Formats the value using the given formatter.

impl Display for SingleTableProjectionError

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

Formats the value using the given formatter.

impl Eq for SingleTableProjectionError

impl Error for SingleTableProjectionError

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 SingleTableProjectionError

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