pub struct StoreSynchronousProxy { /* private fields */ }

Implementations

impl StoreSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event(&self, deadline: Time) -> Result<StoreEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn write_item( &self, payload: &StoreWriteItemRequest, ___deadline: Time ) -> Result<StoreWriteItemResult, Error>

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.
