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" }

Items can be grouped in sections, and may have submenus associated with them. Both items and sections usually have some representation data, such as labels or icons. The type of the associated action (ie whether it is stateful, and what kind of state it has) can influence the representation of the item.

• ResolverNameLookupFlagsv2_60
  Flags to modify lookup behavior.
• Resource
  Applications and libraries often contain binary or textual data that is really part of the application, rather than user data. For instance GtkBuilder .ui files, splashscreen images, GMenu markup XML, CSS files, icons, etc. These are often shipped as files in $datadir/appname, or manually included as literal strings in the code.
• ResourceLookupFlags
  GResourceLookupFlags determine how resource path lookups are handled.
• Seekable
  Seekable is implemented by streams (implementations of InputStream or OutputStream) that support seeking.
• Settings
  The Settings class provides a convenient API for storing and retrieving application settings.

• SocketClient
  SocketClient is a lightweight high-level utility class for connecting to a network host using a connection oriented socket type.

• SocketMsgFlags
• SocketService
  A SocketService is an object that represents a service that is provided to the network or over local sockets. When a new connection is made to the service the incoming signal is emitted.
• SrvTarget
  SRV (service) records are used by some network protocols to provide service-specific aliasing and load-balancing. For example, XMPP (Jabber) uses SRV records to locate the XMPP server for a domain; rather than connecting directly to “example.com” or assuming a specific server hostname like “xmpp.example.com”, an XMPP client would look up the “xmpp-client” SRV record for “example.com”, and then connect to whatever host was pointed to by that record.
• Subprocess

• SubprocessFlags
  Flags to define the behaviour of a Subprocess.

  This class contains a set of options for launching child processes, such as where its standard input and output will be directed, the argument list, the environment, and more.
• 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.
• ThemedIcon
  ThemedIcon is an implementation of Icon that supports icon themes. ThemedIcon contains a list of all of the icons present in an icon theme, so that icons can be looked up quickly. ThemedIcon does not provide actual pixmaps for icons, just the icon names. Ideally something like gtk_icon_theme_choose_icon() should be used to resolve the list of names so that fallback icons work nicely with themes that inherit other themes.
• ThreadedSocketService

• UnixFDMessageUnix
  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 SocketFamily::Unix family). The file descriptors are copied between processes by the kernel.
• UnixInputStreamUnix
  UnixInputStream 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.)

• SocketClientEvent
  Describes an event occurring on a SocketClient. See the event signal for more details.

• SocketListenerEvent
  Describes an event occurring on a SocketListener. See the event signal for more details.
• SocketProtocol
  A protocol identifier is specified when creating a Socket, which is a family/type specific identifier, where 0 means the default protocol for the particular family/type.

  The TLS or DTLS protocol version used by a TlsConnection or GDtlsConnection. 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.
• TlsRehandshakeMode
  When to allow rehandshaking. See TlsConnectionExt::set_rehandshake_mode().
