Expand description
GFileInputStream
provides input streams that take their
content from a file.
GFileInputStream
implements Seekable
, which allows the input
stream to jump to arbitrary positions in the file, provided the
filesystem of the file allows it. To find the position of a file
input stream, use SeekableExt::tell()
. To find out if a file input
stream supports seeking, use vfunc::Gio::Seekable::can_seek
.
To position a file input stream, use vfunc::Gio::Seekable::seek
.

fn query_info( &self, attributes: &str, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<FileInfo, Error>
Queries a file input stream the given @attributes. This function blocks
while querying the stream. For the asynchronous (non-blocking) version
of this function, see g_file_input_stream_query_info_async(). While the
stream is blocked, the stream will set the pending flag internally, and
any other operations on the stream will fail with
IOErrorEnum::Pending
. Read moreSource§fn query_info_async<P: FnOnce(Result<FileInfo, Error>) + 'static>(

fn watch_closure(&self, closure: &impl AsRef<Closure>)
Limits the lifetime of

the object’s reference count drops to zero, the closure will be
invalidated. An invalidated closure will ignore any calls to
