Variants

Parse(String)

Unsupported(String)

UnknownTable(String)

UnknownColumn(String)

AmbiguousColumn(String)

UnknownFunction(String)

TypeMismatch(String)

BadArity

Fields

name: String

expected: String

actual: usize

MissingParam(usize)

VectorDimMismatch

Fields

expected: usize

actual: usize

Cancelled(QueryCancelled)

Routine

Error raised by (or on behalf of) a user-defined SQL / PL/pgSQL routine. Carries an explicit SQLSTATE so EXCEPTION WHEN <condition> handlers and SQLSTATE / SQLERRM report the same code PostgreSQL would.

Fields

sqlstate: String

message: String

Internal(String)

Implementations

impl SQLError

pub fn sqlstate(&self) -> Option<&str>

PostgreSQL SQLSTATE code for the error, mirroring the the current exception-to-state mapping. None for errors that do not carry a defined SQLSTATE.

Trait Implementations

impl Debug for SQLError

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

Formats the value using the given formatter.

impl Display for SQLError

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

Formats the value using the given formatter.

impl Error for SQLError

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 SQLError

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<QueryCancelled> for SQLError

fn from(source: QueryCancelled) -> Self

Converts to this type from the input type.
