Struct gio::FileIOStream
source · #[repr(transparent)]pub struct FileIOStream { /* private fields */ }
Expand description
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.
