Struct BundleStateProvider

Source 
pub struct BundleStateProvider<SP: StateProvider, EDP: ExecutionDataProvider> {
    pub state_provider: SP,
    pub block_execution_data_provider: EDP,
}
Expand description

A state provider that resolves to data from either a wrapped crate::ExecutionOutcome or an underlying state provider.

This struct combines two sources of state data: the execution outcome and an underlying state provider. It can provide state information by leveraging both the post-block execution changes and the pre-existing state data.

Fields§

§state_provider: SP

The inner state provider.

§block_execution_data_provider: EDP

Block execution data.
