Struct gio::FileIOStream

#[repr(transparent)]
pub struct FileIOStream { /* private fields */ }

GFileIOStream provides io streams that both read and write to the same file handle.

GFileIOStream implements Seekable, which allows the io 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 io stream, use SeekableExt::tell().

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

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

Implementations

impl FileIOStream

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

Trait Implementations

impl Clone for FileIOStream

fn clone(&self) -> Self

Returns a copy of the value.

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 Display for FileIOStream

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

Formats the value using the given formatter.

impl Hash for FileIOStream

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

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

This method tests for self and other values to be equal, and is used by ==.

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 FileIOStream

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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 FileIOStream

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for FileIOStream

impl IsA<IOStream> for FileIOStream

impl IsA<Seekable> for FileIOStream
