Enum Error

#[non_exhaustive]
pub enum Error {
    Protocol,
    IsLocked,
    NoSuchObject,
    AlreadyExists,
    InvalidFileFormat,
    MismatchedSchema,
    NoMatchingAttribute,
    WrongType,
    EmptyTable,
}

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.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl ErrorDomain for Error

fn domain() -> Quark

Returns the quark identifying the error domain.

fn code(self) -> i32

Gets the integer representation of the variant.

fn from(code: i32) -> Option<Self>

Tries to convert an integer code to an enum variant.

impl From<Error> for Value

fn from(v: Error) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for Error

type Checker = GenericValueTypeChecker<Error>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for Error

type ParamSpec = ParamSpecEnum

type SetValue = Error

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: Error) -> ParamSpecEnumBuilder<'_, Error>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Error

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 Error

fn cmp(&self, other: &Error) -> 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 Error

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

fn partial_cmp(&self, other: &Error) -> 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.

impl StaticType for Error

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Error

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for Error

type Type = Error

Type to get the Type from.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
