Struct ConsistentProvider

Source 
pub struct ConsistentProvider<N: ProviderNodeTypes> { /* private fields */ }
Expand description

Type that interacts with a snapshot view of the blockchain (storage and in-memory) at time of instantiation, EXCEPT for pending, safe and finalized block which might change while holding this provider.

CAUTION: Avoid holding this provider for too long or the inner database transaction will time-out.

Implementations§

Source§

impl<N: ProviderNodeTypes> ConsistentProvider<N>

Source

pub fn new( storage_provider_factory: ProviderFactory<N>, state: CanonicalInMemoryState, ) -> ProviderResult<Self>

Create a new provider using ProviderFactory and [CanonicalInMemoryState],

Underneath it will take a snapshot by fetching [CanonicalInMemoryState::head_state] and ProviderFactory::database_provider_ro effectively maintaining one single snapshotted view of memory and database.

Source

pub fn get_state( &self, range: RangeInclusive<BlockNumber>, ) -> ProviderResult<Option<ExecutionOutcome>>

Return the last N blocks of state, recreating the ExecutionOutcome.

If the range is empty, or there are no blocks for the given range, then this returns None.
