Struct MemoryStorageAdaptor

pub struct MemoryStorageAdaptor { /* private fields */ }

In-memory storage adaptor for testing and simple use cases.

This implementation stores records in partition-keyed HashMaps. Each partition has its own map.

Example

let storage = StorageAdaptorWrapper::new(MemoryStorageAdaptor::new());
let properties = WalletProperties {
	network: Network::Testnet,
	fingerprint: Fingerprint::default(),
	server_pubkey: None,
};

storage.init_wallet(&properties).await?;

Implementations

impl MemoryStorageAdaptor

pub fn new() -> Self

Creates a new empty in-memory storage.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves a record by primary key.

fn delete<'life0, 'life1, 'async_trait>( &'life0 mut self, partition: u8, pk: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Option<Record>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn incremental_id<'life0, 'async_trait>( &'life0 mut self, partition: u8, ) -> Pin<Box<dyn Future<Output = Result<u32>> + Send + 'async_trait>>

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

Increments the last partition id, then stores and returns the new id.
