Struct TrustedFlatlandProxy 

pub struct TrustedFlatlandProxy { /* private fields */ }

Implementations

impl TrustedFlatlandProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.composition/TrustedFlatland.

pub fn take_event_stream(&self) -> TrustedFlatlandEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn release_image_immediately( &self, image_id: &ContentId, ) -> Result<(), Error>

Releases an image immediately, without waiting for the next present.

pub fn release_image_immediately2( &self, image_id: &ImageId, ) -> Result<(), Error>

Releases an Image immediately, without waiting for the next present. This is a trusted memory-eviction path.

The Image is forcibly unbound from any Layers that currently reference it. Those Layers behave as if their image was simply never set (they are invisible, but retain their image properties) until their next SetLayerImage().

Any pending release fences for the evicted Image’s bindings will signal at the earliest safe point.

This method is only available if Flatland2 is enabled and the session is trusted.
