Struct sp_core::offchain::testing::TestPersistentOffchainDB[][src]

pub struct TestPersistentOffchainDB { /* fields omitted */ }

Sharable “persistent” offchain storage for test.


impl TestPersistentOffchainDB[src]

pub fn new() -> Self[src]

Create a new and empty offchain storage db for persistent items

pub fn apply_offchain_changes(
    &mut self,
    changes: impl Iterator<Item = ((Vec<u8>, Vec<u8>), OffchainOverlayedChange)>

Apply a set of off-chain changes directly to the test backend

pub fn get(&self, key: &[u8]) -> Option<Vec<u8>>[src]

Retrieve a key from the test backend.
