Enum diesel_mysql_spatial::GeometryError

pub enum GeometryError {
    UnsupportedBigEndian,
    WrongType,
    InvalidValue,
    IOError(Error),
    UnsupportedGeoType,
}

The error type for (de-)serialization and conversion errors of spatial datatypes.

Variants

UnsupportedBigEndian

Encountered WKB data in big endian byte order.

Should not occur as MySQL only uses little endian for the spatial datatypes.

WrongType

Unexpected data type encountered (e.g. a Polygon instead of a Point).

InvalidValue

A conversion could not be performed because a value precondition was not fulfilled

For example data_types::BoundingBox requires a Polygon in a specific shape.

IOError(Error)

Deserialization failed because of a format mismatch or an I/O error happened in a underlying layer.

UnsupportedGeoType

Encountered an unsupported geometry while serializing.

Trait Implementations

impl Debug for GeometryError

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

Formats the value using the given formatter.

impl Display for GeometryError

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

Formats the value using the given formatter.

impl Error for GeometryError

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
