Struct gio::OutputStream

pub struct OutputStream { /* private fields */ }

GOutputStream is a base class for implementing streaming output.

It has functions to write to a stream (OutputStreamExt::write()), to close a stream (OutputStreamExt::close()) and to flush pending writes (OutputStreamExt::flush()).

To copy the content of an input stream to an output stream without manually handling the reads and writes, use OutputStreamExt::splice().

See the documentation for IOStream for details of thread safety of streaming APIs.

All of these functions have async variants too.

All classes derived from GOutputStream should implement synchronous writing, splicing, flushing and closing streams, but may implement asynchronous versions.

This is an Abstract Base Class, you cannot instantiate it.

Implements

OutputStreamExt, [trait@glib::ObjectExt], OutputStreamExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl OutputStream

pub const NONE: Option<&'static OutputStream> = None

Trait Implementations

impl Clone for OutputStream

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 OutputStream

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

Formats the value using the given formatter.

impl HasParamSpec for OutputStream

type ParamSpec = ParamSpecObject

type SetValue = OutputStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for OutputStream

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<T: OutputStreamImpl> IsSubclassable<T> for OutputStream

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for OutputStream

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for OutputStream

type Parent = Object

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

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

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 OutputStream

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

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 OutputStream

fn static_type() -> Type

Returns the type identifier of Self.
