Struct FileIOStream

pub struct FileIOStream { /* private fields */ }

GFileIOStream provides I/O streams that both read and write to the same file handle.

GFileIOStream implements Seekable, which allows the I/O stream to jump to arbitrary positions in the file and to truncate the file, provided the filesystem of the file supports these operations.

To find the position of a file I/O stream, use SeekableExt::tell().

To find out if a file I/O stream supports seeking, use SeekableExt::can_seek(). To position a file I/O stream, use SeekableExt::seek(). To find out if a file I/O stream supports truncating, use SeekableExt::can_truncate(). To truncate a file I/O stream, use SeekableExt::truncate().

The default implementation of all the GFileIOStream operations and the implementation of Seekable just call into the same operations on the output stream.

Implements

FileIOStreamExt, IOStreamExt, [trait@glib::ObjectExt], SeekableExt, IOStreamExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl FileIOStream

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

Trait Implementations

impl Clone for FileIOStream

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 FileIOStream

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

Formats the value using the given formatter.

impl HasParamSpec for FileIOStream

type ParamSpec = ParamSpecObject

type SetValue = FileIOStream

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FileIOStream

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 FileIOStream

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 FileIOStream

type Parent = IOStream

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

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 FileIOStream

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 FileIOStream

fn static_type() -> Type

Returns the type identifier of Self.

impl IsA<IOStream> for FileIOStream
