Struct PollableOutputStream

pub struct PollableOutputStream { /* private fields */ }

GPollableOutputStream is implemented by OutputStreams that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

Some classes may implement GPollableOutputStream but have only certain instances of that class be pollable. If PollableOutputStreamExt::can_poll() returns false, then the behavior of other GPollableOutputStream methods is undefined.

Implements

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

GLib type: GObject with reference counted clone semantics.

Implementations

impl PollableOutputStream

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

Trait Implementations

impl Clone for PollableOutputStream

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 PollableOutputStream

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

Formats the value using the given formatter.

impl HasParamSpec for PollableOutputStream

type ParamSpec = ParamSpecObject

type SetValue = PollableOutputStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PollableOutputStream

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 PollableOutputStream

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<OT: ObjectType> PartialEq<OT> for PollableOutputStream

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 PollableOutputStream

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 PollableOutputStream

fn static_type() -> Type

Returns the type identifier of Self.

impl IsA<PollableOutputStream> for ConverterOutputStream
