Struct BalloonControllerProxy

pub struct BalloonControllerProxy { /* private fields */ }

Implementations

impl BalloonControllerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.virtualization/BalloonController.

pub fn take_event_stream(&self) -> BalloonControllerEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_balloon_size( &self, ) -> QueryResponseFut<(u32, u32), DefaultFuchsiaResourceDialect>

Get the current and requested number of pages in the memory balloon.

current_num_pages is the number of pages balloon has right now. requested_num_pages is the desired number of pages in the balloon.

‘current_num_pages’ corresponds to the ‘actual’ virtio-balloon config field ‘requested_num_pages’ corresponds to the ‘num_pages’ virtio-balloon config field.

pub fn request_num_pages(&self, requested_num_pages: u32) -> Result<(), Error>

Request a number of pages to be supplied to the memory balloon.

If requested_num_pages is greater than the current_num_pages config value, the guest driver SHOULD provide additional pages to the memory balloon. If requested_num_pages is less than the ‘current_num_pages’ config value, the guest driver MAY reclaim pages from the memory balloon.

pub fn get_mem_stats( &self, ) -> QueryResponseFut<(i32, Option<Vec<MemStat>>), DefaultFuchsiaResourceDialect>

Get memory statistics of the guest instance.
