Trait containing all ContentProvider methods.

Implementors

ContentProvider

Provided Methods

fn content_changed(&self)

Emits the ::content-changed signal.

fn formats(&self) -> ContentFormats

Gets the formats that the provider can provide its current contents in.

Returns

The formats of the provider

fn storable_formats(&self) -> ContentFormats

Gets the formats that the provider suggests other applications to store the data in.

An example of such an application would be a clipboard manager.

This can be assumed to be a subset of formats().

Returns

The storable formats of the provider

fn write_mime_type_async<P: FnOnce(Result<(), Error>) + 'static>( &self, mime_type: &str, stream: &impl IsA<OutputStream>, io_priority: Priority, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

Asynchronously writes the contents of @self to @stream in the given @mime_type.

The given mime type does not need to be listed in the formats returned by formats(). However, if the given GType is not supported, G_IO_ERROR_NOT_SUPPORTED will be reported.

The given @stream will not be closed.

mime_type

the mime type to provide the data in

stream

the GOutputStream to write to

io_priority

I/O priority of the request.

cancellable

optional GCancellable object, None to ignore.

callback

callback to call when the request is satisfied

fn write_mime_type_future( &self, mime_type: &str, stream: &(impl IsA<OutputStream> + Clone + 'static), io_priority: Priority, ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn connect_content_changed<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted whenever the content provided by this provider has changed.

fn connect_formats_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

fn connect_storable_formats_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
