GSeekableIface: @g_iface: The parent interface. @tell: Tells the current location within a stream. @can_seek: Checks if seeking is supported by the stream. @seek: Seeks to a location within a stream. @can_truncate: Checks if truncation is supported by the stream. @truncate_fn: Truncates a stream.

Provides an interface for implementing seekable functionality on I/O Streams.

Trait Implementations

impl Clone for _GSeekableIface

fn clone(&self) -> _GSeekableIface

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for _GSeekableIface

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

Formats the value using the given formatter.

impl PartialEq for _GSeekableIface

fn eq(&self, other: &_GSeekableIface) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
