Errors that can occur during query parsing and execution.

Variants

ParseError(String)

SQL syntax or parsing error.

TableNotFound(String)

Table not found in schema.

ColumnNotFound

Column not found in table.

Fields

table: String

column: String

ParameterNotFound(usize)

Query parameter not provided.

TypeMismatch

Type mismatch between expected and actual value.

Fields

expected: String

actual: String

UnsupportedFeature(String)

SQL feature not supported.

ConstraintViolation(String)

Constraint violation (e.g., duplicate primary key, NOT NULL violation).

Store(StoreError)

Underlying store error.

Json(Error)

JSON serialization/deserialization error.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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 From<Error> for QueryError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<StoreError> for QueryError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
