A host-implemented store (3.4.1). Every call is polled on the task of the decision that made it.

Required Methods

fn contract(&self) -> &StoreContract

The store’s contract; prepare compares it with the plan’s.

fn get<'a>( &'a self, namespace: &'a str, scope: &'a str, key_id: &'a str, call: StoreCall, ) -> BoxFuture<'a, Result<Stored, StoreFailure>>

The entry under key_id, if any, and the namespace and scope generations, read atomically.

fn put<'a>( &'a self, namespace: &'a str, key_id: &'a str, bytes: Vec<u8>, terms: PutTerms, call: StoreCall, ) -> BoxFuture<'a, Result<PutAnswer, StoreFailure>>

Store bytes under key_id if terms still hold.

fn delete<'a>( &'a self, namespace: &'a str, key_id: &'a str, call: StoreCall, ) -> BoxFuture<'a, Result<(), StoreFailure>>

Remove one entry.

fn invalidate<'a>( &'a self, namespace: &'a str, selector: StoreSelector, call: StoreCall, ) -> BoxFuture<'a, Result<Invalidated, StoreFailure>>

Atomically advance the selected generation and make the entries it covers unreadable.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
