This is the asynchronous version of 'GI.Gio.Interfaces.Initable.Initable'; it behaves the same
in all ways except that initialization is asynchronous. For more details
see the descriptions on 'GI.Gio.Interfaces.Initable.Initable'.

A class may implement both the 'GI.Gio.Interfaces.Initable.Initable' and 'GI.Gio.Interfaces.AsyncInitable.AsyncInitable' interfaces.

Users of objects implementing this are not intended to use the interface
method directly; instead it will be used automatically in various ways.
For C applications you generally just call @/g_async_initable_new_async()/@
directly, or indirectly via a @/foo_thing_new_async()/@ wrapper. This will call
'GI.Gio.Interfaces.AsyncInitable.asyncInitableInitAsync' under the cover, calling back with 'Nothing' and
a set @/GError/@ on failure.

A typical implementation might look something like this:

{- |
Starts asynchronous initialization of the object implementing the
interface. This must be done before any real use of the object after
initial construction. If the object also implements 'GI.Gio.Interfaces.Initable.Initable' you can
optionally call 'GI.Gio.Interfaces.Initable.initableInit' instead.

This method is intended for language bindings. If writing in C,
@/g_async_initable_new_async()/@ should typically be used instead.

When the initialization is finished, /@callback@/ will be called. You can
then call 'GI.Gio.Interfaces.AsyncInitable.asyncInitableInitFinish' to get the result of the
initialization.

Implementations may also support cancellation. If /@cancellable@/ is not
'Nothing', then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
'GI.Gio.Enums.IOErrorEnumCancelled' will be returned. If /@cancellable@/ is not 'Nothing', and
the object doesn\'t support cancellable initialization, the error
'GI.Gio.Enums.IOErrorEnumNotSupported' will be returned.

As with 'GI.Gio.Interfaces.Initable.Initable', if the object is not initialized, or initialization
returns with an error, then all operations on the object except
'GI.GObject.Objects.Object.objectRef' and 'GI.GObject.Objects.Object.objectUnref' are considered to be invalid, and
have undefined behaviour. They will often fail with @/g_critical()/@ or
@/g_warning()/@, but this must not be relied on.

Callers should not assume that a class which implements 'GI.Gio.Interfaces.AsyncInitable.AsyncInitable' can
be initialized multiple times; for more information, see 'GI.Gio.Interfaces.Initable.initableInit'.
If a class explicitly supports being initialized multiple times,
implementation requires yielding all subsequent calls to @/init_async()/@ on the
results of the first call.

For classes that also support the 'GI.Gio.Interfaces.Initable.Initable' interface, the default
implementation of this method will run the 'GI.Gio.Interfaces.Initable.initableInit' function
in a thread, so if you want to support asynchronous initialization via
threads, just implement the 'GI.Gio.Interfaces.AsyncInitable.AsyncInitable' interface without overriding
any interface methods.

{- |
Helper function for constructing 'GI.Gio.Interfaces.AsyncInitable.AsyncInitable' object. This is
similar to 'GI.GObject.Objects.Object.objectNewv' but also initializes the object asynchronously.

When the initialization is finished, /@callback@/ will be called. You can
then call 'GI.Gio.Interfaces.AsyncInitable.asyncInitableNewFinish' to get the new object and check
for any errors.

/Since: 2.22/
