    Other,
}

A list of error categories.

It is used with the Error type.

Use _ to match “all other errors” in match expression because it has #[non_exhaustive] attribute.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OciError

Error from an underlying Oracle client library.

DpiError

Error from an underlying ODPI-C layer.

NullValue

Error when NULL value is got but the target rust type cannot handle NULL. Use Option<...> in this case.

ParseError

Error when conversion from a string to an Oracle value fails

OutOfRange

Error when conversion from a type to another fails due to out-of-range

InvalidArgument

Error when an unacceptable argument is passed

InvalidTypeConversion

Error when conversion from a type to another is not allowed.

InvalidBindIndex

Error when the bind parameter index is out of range. (one based)

InvalidBindName

Error when the bind parameter name is not in the SQL.

InvalidColumnIndex

Error when the column index is out of range. (zero based)

InvalidColumnName

Error when the column name is not in the SQL.

InvalidAttributeName

Error when the specified attribute name is not found.

InvalidOperation

Error when invalid method is called such as calling execute for select statements.

UninitializedBindValue

Error when an uninitialized bind value is accessed. Bind values must be initialized by Statement::bind, Statement::execute or Connection::execute in advance.

NoDataFound

Error when no more rows exist in the SQL.

BatchErrors

Error when BatchBuilder::with_batch_errors is set and Batch::execute fails by supplied batch data. See “Error Handling with batch errors”

InternalError

Internal error. When you get this error, please report it with a test case to reproduce it.

Other

A custom error that does not match any other error kind.

This is intended to be used outside of this crate.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ErrorKind

fn cmp(&self, other: &ErrorKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ErrorKind

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for ErrorKind

fn partial_cmp(&self, other: &ErrorKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
