Available on crate feature sea-ql only.

Error returned by DataRow::try_get.

Variants

ColumnNotFound(String)

A column name passed to try_get does not exist in this row.

IndexOutOfBounds(usize)

A column index passed to try_get is out of bounds.

UnexpectedNull

The column value is NULL but the target type is not Option<T>.

TypeMismatch

The stored Value variant cannot be converted to the requested type.

Fields

expected: &'static str

got: &'static str

OutOfRange(&'static str)

The stored numeric value is outside the representable range of the target type.

Trait Implementations

impl Debug for TypeError

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

Formats the value using the given formatter.

impl Display for TypeError

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

Formats the value using the given formatter.

impl Error for TypeError

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<TypeError> for Error

fn from(source: TypeError) -> Self

Converts to this type from the input type.
