Struct gio::BufferedOutputStream

pub struct BufferedOutputStream { /* private fields */ }

Buffered output stream implements FilterOutputStream and provides for buffered writes.

By default, GBufferedOutputStream’s buffer size is set at 4 kilobytes.

To create a buffered output stream, use new(), or new_sized() to specify the buffer’s size at construction.

To get the size of a buffer within a buffered input stream, use BufferedOutputStreamExt::buffer_size(). To change the size of a buffered output stream’s buffer, use BufferedOutputStreamExt::set_buffer_size(). Note that the buffer’s size cannot be reduced below the size of the data within the buffer.

Properties

auto-grow

Whether the buffer should automatically grow.

Readable | Writeable

buffer-size

The size of the backend buffer, in bytes.

Readable | Writeable | Construct

FilterOutputStream

base-stream

Readable | Writeable | Construct Only

close-base-stream

Whether the base stream should be closed when the filter stream is closed.

GLib type: GObject with reference counted clone semantics.

Implementations

impl BufferedOutputStream

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

pub fn new(base_stream: &impl IsA<OutputStream>) -> BufferedOutputStream

Creates a new buffered output stream for a base stream.

base_stream

a #GOutputStream.

Returns

a #GOutputStream for the given @base_stream.

pub fn new_sized( base_stream: &impl IsA<OutputStream>, size: usize, ) -> BufferedOutputStream

Creates a new buffered output stream with a given buffer size.

base_stream

a #GOutputStream.

size

a #gsize.

Returns

a #GOutputStream with an internal buffer set to @size.

pub fn builder() -> BufferedOutputStreamBuilder

Creates a new builder-pattern struct instance to construct BufferedOutputStream objects.

This method returns an instance of BufferedOutputStreamBuilder which can be used to create BufferedOutputStream objects.

Trait Implementations

impl Clone for BufferedOutputStream

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 BufferedOutputStream

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

Formats the value using the given formatter.

impl Default for BufferedOutputStream

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for BufferedOutputStream

type ParamSpec = ParamSpecObject

type SetValue = BufferedOutputStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for BufferedOutputStream

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 BufferedOutputStream

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 BufferedOutputStream

type Parent = FilterOutputStream

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

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 BufferedOutputStream

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 BufferedOutputStream

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for BufferedOutputStream

impl IsA<FilterOutputStream> for BufferedOutputStream

impl IsA<OutputStream> for BufferedOutputStream

impl IsA<Seekable> for BufferedOutputStream
