Represents all errors from the SQL Builder

Variants

FieldMissing(String)

The field is not mapped to a column or SQL expression. Contains the field name.

PredicateMissing(String)

The field is not mapped to a column or SQL expression. Contains the field name.

JoinMissing(String, String)

The join is not mapped to a column or SQL expression. Contains the join name and the table name.

MergeMissing(String)

The merge is not mapped. Contains the field name.

SelectionMissing(String)

The selection is not known to the mapper. Contains the field name.

RoleRequired(String, String)

The field requires a role that the query does not have. Contains the role and the query_path.

FilterInvalid(String)

The filter expects other arguments. Typically raised by custom functions (FN) if the number of arguments is wrong.

QueryParamMissing(String)

A query expression requires a query parameter, that is not provided. Contains the parameter.

QueryParamInvalid(String, String)

The query parameter that is required by the query expression is wrong. Contains the parameter and the details.

PredicateArgumentMissing(String)

A predicate requires more arguments, than the toql q uery provided, contains the predicate.

KeyMismatch(String, String)

An key cannot be set, because type is wrong or key is composite key

PathUnexpected(String)

A path was found for a selection that only exists in root, such as $all, $mut, $cnt

Trait Implementations

impl Debug for SqlBuilderError

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

Formats the value using the given formatter.

impl Display for SqlBuilderError

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

Formats the value using the given formatter.

impl Error for SqlBuilderError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<SqlBuilderError> for ToqlError

fn from(source: SqlBuilderError) -> Self

Converts to this type from the input type.
