Struct fidl_examples_keyvaluestore_usegenericvalues::StoreProxy

pub struct StoreProxy { /* private fields */ }

Implementations

impl StoreProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for Store

pub fn take_event_stream(&self) -> StoreEventStream

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

Panics

Panics if the event stream was already taken.

pub fn write_item( &self, payload: StoreWriteItemRequest ) -> QueryResponseFut<StoreWriteItemResult>

Writes an item to the store.

Since the value stored in the key-value store can now be different from the input (if the WriteOptions.CONCAT flag is set), we need to return the resulting Value to the requester.

We use an (anonymous) table and a (named) flexible union as the request and response payload, respectively, to allow for easier future evolution. Both of these types are flexible, meaning that adding or removing members is binary-compatible. This makes them much easier to evolve that the struct types that were previously used, which cannot be changed after release without breaking ABI.
