Set of possible errors pgrx might return while working with Postgres SPI

Variants

SpiError(SpiErrorCodes)

An underlying SpiErrorCodes given to us by Postgres

DatumError(TryFromDatumError)

Some kind of problem understanding how to convert a Datum

PreparedStatementArgumentMismatch

Fields

expected: usize

got: usize

An incorrect number of arguments were supplied to a prepared statement

InvalidPosition

SpiTupleTable is positioned outside its bounds

CursorNotFound(String)

Postgres could not find the specified cursor by name

NoTupleTable

The pg_sys::SPI_tuptable is null

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<SpiErrorCodes> for Error

fn from(source: SpiErrorCodes) -> Self

Converts to this type from the input type.

impl From<TryFromDatumError> for Error

fn from(source: TryFromDatumError) -> Self

Converts to this type from the input type.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
