Struct MemoryOutputStream

pub struct MemoryOutputStream { /* private fields */ }

GMemoryOutputStream is a class for using arbitrary memory chunks as output for GIO streaming output operations.

As of GLib 2.34, GMemoryOutputStream trivially implements PollableOutputStream: it always polls as ready.

Properties

data

Pointer to buffer where data will be written.

Readable | Writeable | Construct Only

data-size

Size of data written to the buffer.

Readable

destroy-function

Function called with the buffer as argument when the stream is destroyed.

Readable | Writeable | Construct Only

realloc-function

Function with realloc semantics called to enlarge the buffer.

Readable | Writeable | Construct Only

size

Current size of the data buffer.

Implements

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

GLib type: GObject with reference counted clone semantics.

Implementations

impl MemoryOutputStream

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

pub fn new_resizable() -> MemoryOutputStream

Creates a new #GMemoryOutputStream, using g_realloc() and g_free() for memory allocation.

Trait Implementations

impl Clone for MemoryOutputStream

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 MemoryOutputStream

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

Formats the value using the given formatter.

impl HasParamSpec for MemoryOutputStream

type ParamSpec = ParamSpecObject

type SetValue = MemoryOutputStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for MemoryOutputStream

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 MemoryOutputStream

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 MemoryOutputStream

type Parent = OutputStream

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

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 MemoryOutputStream

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 MemoryOutputStream

fn static_type() -> Type

Returns the type identifier of Self.
