Struct gdk4::ContentSerializer

pub struct ContentSerializer { /* private fields */ }

A ContentSerializer is used to serialize content for inter-application data transfers.

The ContentSerializer transforms an object that is identified by a GType into a serialized form (i.e. a byte stream) that is identified by a mime type.

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

Also see ContentDeserializer.

Implementations

impl ContentSerializer

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

Gets the cancellable for the current operation.

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

Returns

the cancellable for the current operation

pub fn type_(&self) -> Type

Gets the GType to of the object to serialize.

Returns

the GType for the current operation

pub fn mime_type(&self) -> GString

Gets the mime type to serialize to.

Returns

the mime type for the current operation

pub fn output_stream(&self) -> OutputStream

Gets the output stream for the current operation.

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

Returns

the output stream for the current operation

pub fn value(&self) -> Value

Gets the GValue to read the object to serialize from.

Returns

the GValue for the current operation

pub fn return_success(&self)

Indicate that the serialization has been successfully completed.

impl ContentSerializer

pub fn priority(&self) -> Priority

Gets the I/O priority for the current operation.

This is the priority that was passed to content_serialize_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 serialization has ended with an error.

This function consumes @error.

error

a GError

Trait Implementations

impl Clone for ContentSerializer

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentSerializer

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

Formats the value using the given formatter.

impl HasParamSpec for ContentSerializer

type ParamSpec = ParamSpecObject

type SetValue = ContentSerializer

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ContentSerializer

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

where H: Hasher,

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 ContentSerializer

fn cmp(&self, other: &Self) -> 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 ParentClassIs for ContentSerializer

type Parent = Object

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

fn eq(&self, other: &OT) -> 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<OT: ObjectType> PartialOrd<OT> for ContentSerializer

fn partial_cmp(&self, other: &OT) -> 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 ContentSerializer

fn static_type() -> Type

Returns the type identifier of Self.
