impl Store for MemoryStore

fn put<'life0, 'async_trait>( &'life0 self, hash: Hash, data: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Store data by its hash Returns true if newly stored, false if already existed
