Trait ViewLocalServerHandler 

pub trait ViewLocalServerHandler<___T: Transport = Channel> {
    // Required method
    fn present(
        &mut self,
        request: Request<Present, ___T>,
    ) -> impl Future<Output = ()>;
}

A server handler for the View protocol.

See View for more details.

Required Methods

fn present( &mut self, request: Request<Present, ___T>, ) -> impl Future<Output = ()>

Provides the View with an attachment point to Scenic’s scene graph.

When Present() is called the View’s implementation should create a View resource within Scenic by providing it with the view_token (using a fuchsia.ui.gfx.CreateResourceCmd and fuchsia.ui.gfx.ViewArgs).

Then the implementation should attach its graphical content to the newly-created View resource using a fuchsia.ui.gfx.AddChildCmd.

If the implementation already owns a View resource (because Present() had already been called before), then it should terminate the connection with an error.

TODO(https://fxbug.dev/42098670): Allow re-parenting Views with a new Present() call.

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.
