Struct fidl_fuchsia_memorypressure::ProviderProxy

pub struct ProviderProxy { /* private fields */ }

Implementations

impl ProviderProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.memorypressure/Provider.

pub fn take_event_stream(&self) -> ProviderEventStream

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

Panics

Panics if the event stream was already taken.

pub fn register_watcher( &self, watcher: ClientEnd<WatcherMarker>, ) -> Result<(), Error>

Used to register for memory pressure level changes. watcher: memory pressure Watcher channel that the Provider will use to send level change messages to the client.

The current memory pressure level is immediately sent to the watcher when this method is called.

It is recommended that the root job in a component tree register for changes, rather than having individual jobs further down the tree register individually. A low client count will help minimize system churn due to a large number of memory pressure messages in transit at the same time. Also, the more context a job has, the better equipped it will be to react to memory pressure by controlling the behavior of children jobs in its tree.
