Error codes that identify various errors that can occur while using Builder.

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.

InvalidTypeFunction

A type-func attribute didn’t name a function that returns a GType.

UnhandledTag

The input contained a tag that Builder can’t handle.

MissingAttribute

An attribute that is required by Builder was missing.

InvalidAttribute

Builder found an attribute that it doesn’t understand.

InvalidTag

Builder found a tag that it doesn’t understand.

MissingPropertyValue

A required property value was missing.

InvalidValue

Builder couldn’t parse some attribute value.

VersionMismatch

The input file requires a newer version of GTK.

DuplicateId

An object id occurred twice.

ObjectTypeRefused

A specified object type is of the same type or derived from the type of the composite class being extended with builder XML.

TemplateMismatch

The wrong type was specified in a composite class’s template XML

InvalidProperty

The specified property is unknown for the object class.

InvalidSignal

The specified signal is unknown for the object class.

InvalidId

An object id is unknown.

InvalidFunction

A function could not be found. This often happens when symbols are set to be kept private. Compiling code with -rdynamic or using the gmodule-export-2.0 pkgconfig module can fix this problem.

Trait Implementations

impl Clone for BuilderError

fn clone(&self) -> BuilderError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuilderError

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

Formats the value using the given formatter.

impl ErrorDomain for BuilderError

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<BuilderError> for Value

fn from(v: BuilderError) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for BuilderError

type Checker = GenericValueTypeChecker<BuilderError>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for BuilderError

type ParamSpec = ParamSpecEnum

type SetValue = BuilderError

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for BuilderError

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 BuilderError

fn cmp(&self, other: &BuilderError) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for BuilderError

fn eq(&self, other: &BuilderError) -> 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.

impl PartialOrd for BuilderError

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for BuilderError

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for BuilderError

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 BuilderError

type Type = BuilderError

Type to get the Type from.

impl Copy for BuilderError

impl Eq for BuilderError

impl StructuralPartialEq for BuilderError
