Struct ContentDeserializer

pub struct ContentDeserializer { /* private fields */ }

A ContentDeserializer is used to deserialize content received via inter-application data transfers.

The ContentDeserializer transforms serialized content that is identified by a mime type into an object identified by a GType.

GTK provides serializers and deserializers for common data types such as text, colors, images or file lists. To register your own deserialization functions, use content_register_deserializer().

Also see ContentSerializer.

GLib type: GObject with reference counted clone semantics.

Implementations

impl ContentDeserializer

pub fn cancellable(&self) -> Option<Cancellable>

Gets the cancellable for the current operation.

This is the GCancellable that was passed to content_deserialize_async().

Returns

the cancellable for the current operation

pub fn type_(&self) -> Type

Gets the GType to create an instance of.

Returns

the GType for the current operation

pub fn input_stream(&self) -> InputStream

Gets the input stream for the current operation.

This is the stream that was passed to content_deserialize_async().

Returns

the input stream for the current operation

pub fn mime_type(&self) -> GString

Gets the mime type to deserialize from.

Returns

the mime type for the current operation

pub fn value(&self) -> Value

Gets the GValue to store the deserialized object in.

Returns

the GValue for the current operation

pub fn return_success(&self)

Indicate that the deserialization has been successfully completed.

impl ContentDeserializer

pub fn set_value(&self, value: Value)

pub fn priority(&self) -> Priority

Gets the I/O priority for the current operation.

This is the priority that was passed to content_deserialize_async().

Returns

the I/O priority for the current operation

pub fn value_as<V: for<'b> FromValue<'b> + 'static>(&self) -> V

Similar to Self::value but panics if the value is of a different type.

pub fn return_error(&self, error: Error)

Indicate that the deserialization has ended with an error.

This function consumes @error.

error

a GError

Trait Implementations

impl Clone for ContentDeserializer

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for ContentDeserializer

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

Formats the value using the given formatter.

impl HasParamSpec for ContentDeserializer

type ParamSpec = ParamSpecObject

type SetValue = ContentDeserializer

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

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, ContentDeserializer>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ContentDeserializer

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

where H: Hasher,

Hashes the memory address of this object.

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 ContentDeserializer

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ParentClassIs for ContentDeserializer

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for ContentDeserializer

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for ContentDeserializer

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ContentDeserializer

fn static_type() -> Type

Returns the type identifier of Self.
