§Rust GIO bindings

Rust bindings and wrappers for GIO, part of gtk-rs-core.

GIO 2.56 is the lowest supported version for the underlying library.

§Minimum supported Rust version

Currently, the minimum supported Rust version is 1.70.0.

§Documentation

§Using

We recommend using crates from crates.io, as demonstrated here.

If you want to track the bleeding edge, use the git dependency instead:

[dependencies]
gio = { git = "https://github.com/gtk-rs/gtk-rs-core.git", package = "gio" }

Avoid mixing versioned and git crates like this:

# This will not compile
[dependencies]
gio = "0.13"
gio = { git = "https://github.com/gtk-rs/gtk-rs-core.git", package = "gio" }

The flags listed in the enum are some commonly available flags, but the values used for them are the same as on the platform, and any other flags are passed in/out as is. So to use a platform specific flag, just include the right system header and pass in the flag.
  • SocketService

  • Task
    Task provides idiomatic access to gio’s GTask API, for instance by being generic over their value type, while not completely departing from the underlying C API. Task is Send and Sync and requires its value to also be Send and Sync, thus is useful to to implement gio style asynchronous tasks that run in threads. If you need to only run tasks in glib main loop see the LocalTask type.
  • TcpConnection
    This is the subclass of SocketConnection that is created for TCP/IP sockets.
  • TcpWrapperConnection
    A GTcpWrapperConnection can be used to wrap a IOStream that is based on a Socket, but which is not actually a SocketConnection. This is used by SocketClient so that it can always return a SocketConnection, even when the connection it has actually created is not directly a SocketConnection.

    This SocketControlMessage contains a UnixFDList. It may be sent using SocketExtManual::send_message() and received using SocketExtManual::receive_message() over UNIX sockets (ie: sockets in the G_SOCKET_FAMILY_UNIX family). The file descriptors are copied between processes by the kernel.
  • UnixInputStreamUnix
    GUnixInputStream implements InputStream for reading from a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)
  • UnixMountEntryUnix
    Defines a Unix mount entry (e.g. /media/cdrom). This corresponds roughly to a mtab entry.
  • UnixMountMonitorUnix
    Watches #GUnixMounts for changes.
  • UnixMountPointUnix
    Defines a Unix mount point (e.g. /dev). This corresponds roughly to a fstab entry.
  • UnixOutputStreamUnix
    GUnixOutputStream implements OutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)
  • UnixSocketAddressUnix
    Support for UNIX-domain (also known as local) sockets, corresponding to struct sockaddr_un.
  • Vfs
    Entry point for using GIO functionality.
  • Volume
    The GVolume interface represents user-visible objects that can be mounted. For example, a file system partition on a USB flash drive, or an optical disc inserted into a disc drive.
  • VolumeMonitor
    GVolumeMonitor is for listing the user interesting devices and volumes on the computer. In other words, what a file selector or file manager would show in a sidebar.
  • WatcherId
  • WriteOutputStream
    GLib type: GObject with reference counted clone semantics.
  • ZlibCompressor
    GZlibCompressor is an implementation of Converter that compresses data using zlib.
  • ZlibDecompressor
    GZlibDecompressor is an implementation of Converter that decompresses data compressed with zlib.

The integer values of these versions are sequential to ensure newer known protocol versions compare greater than older known versions. Any known DTLS protocol version will compare greater than any SSL or TLS protocol version. The protocol version may be Unknown if the TLS backend supports a newer protocol version that GLib does not yet know about. This means that it’s possible for an unknown DTLS protocol version to compare less than the TLS protocol versions.
